¡Hellow!
For this problem, lets recabe information:
v (Velocity) = 10 m/s
a (Aceleration) = 1 m/s²
t (Time) = 1/4 min = 25 s
d (Distance) = ?
v' (Final velocity) = ?
First, for calculate distance, lets applicate formula:
[tex]\boxed{\boxed{\text{d = Vo * t + (a * t}^{2})\text{ * 0,5} } }[/tex]
Lets replace according we information and let's resolve it:
d = 10 m/s * 25 s + (1 m/s² * (25 s)²) * 0,5
d = 250 m + (625 m) * 0,5
d = 2,5 m + 312,5 m
d = 314 meters.
Now, for calculate final speed, lets applicate formula:
[tex]\boxed{\boxed{\text{v' = v + a * t} } }[/tex]
Lets replace according we information and let's resolve it:
v' = 10 m/s + 1 m/s² * 25 s
v' = 10 m/s + 25 m/s
v' = 35 m/s
¿Good Luck?

Answer:
The 2 forces are a Push and a Pull
Mass is the resistance of change in speed or position when adding force.
Weight is the force of gravity
Tension Force is the pulling force transmitted through a string cable or chain. The formula for this is T = mg + ma.
It gives the particle the same acceleration as all those actual forces together as described by the Newton's second law of motion.
An unbalanced force is when there is 2 forces on opposites of an object both are adding force but one side is stronger than the other.
Friction is a force that heats things up. This happens when we rub our hands together and the heat that is generated from the friction makes our hands warmer.
Static friction is what keeps the box from moving without being pushed, and it must be overcome with a sufficient opposing force before the box will move. Kinetic friction (also referred to as dynamic friction) is the force that resists the relative movement of the surfaces once they're in motion.

What are the relationships between the different wave properties (frequency, wavelength, wave speed, period, amplitude)
Ex) As ___ increases, ___ increases/decreases/remains the same.
Answer:
As frequency (cycles per second) increases the wavelength decreases.
As frequency increases the period also decreases
If wave speed or velocity increases, so too does the frequency
Amplitude of a wave is totally independent of frequency, period etc. So it remains the same as frequency shifts. Like FM radio the amplitude remains the same as the frequency of the broadcast modulates.
Explanation:
F= 1/t Frequency is inversely proportional to time (wavelength)
Period is the time it takes for one wave cycle to complete Period is 1/f
++++++++++++++++++++++++++++++++++++
vw=λT Speed of propagation vw= wavelength x T time
vw=fλ Knowing frequency multiply times wavelength to get wave speed.
++++++++++++++++++++++++++++++++
Amplitude varies only as the energy applied varies. Like transmission power, in a 60 hz power feed the amplitude can be 120, 230, 460 volts (note these nominal amplitudes are RMS root mean squared or .707 of the peak of the waveform).

What voltage produces a current of 100 amps with a resistance of 50 ohms?
Answer:
To find the Voltage, ( V ) [ V = I x R ] V (volts) = I (amps) x R (Ω)
To find the Current, ( I ) [ I = V ÷ R ] I (amps) = V (volts) ÷ R (Ω)
To find the Resistance, ( R ) [ R = V ÷ I ] R (Ω) = V (volts) ÷ I (amps)
To find the Power (P) [ P = V x I ] P (watts) = V (volts) x I (amps)

What is the wave velocity if the wave length is 100 cm and the frequency is 2 Hz?
Answer:
velocity = 2m/s
using v=fΠ
convert 100 CM to m
Answer:
200 cm per second
Explanation:
The equation for wave velocity=wavelength x frequency, since the wavelength is 100 and the frequency is two, the equation would be 100 x 2, which equals 200. Therefore, the correct answer is 200 cm per second.

Study the motion map shown. Some of the vectors have been circled. A long black arrow pointing right labeled x. Above that are 5 green arrows of the same length pointing right, positioned end to end. Next to these are 2 shorter green arrows, each with small yellow arrows pointing left just above that are circled. Farther up from the line is a point. Much farther above that are 3 green arrows each longer than the previous. Above the green arrows are 3 yellow arrows of equal length pointed left, each circled. What do the circled vectors represent? distance speed velocity acceleration
Answer:
The object starts away from the origin and then moves toward the origin at a constant velocity. Next, it stops for one second. Finally, it moves away from the origin at a greater constant velocity.
Explanation:
Sample Response: The object starts away from the origin and then moves toward the origin at a constant velocity. Next, it stops for one second. Finally, it moves away from the origin at a greater constant velocity.
What did you include in your description? Check all that apply.
The object starts away from the origin.
The object moves toward the origin at a constant velocity.
The object stops for one second.
The object moves away from the origin at a greater constant velocity.
The circled vectors represent speed.
What is speed?
The is the ratio of distance traveled to time of motion. Speed is a scalar quantity because it has only only magnitude.
From the map, as the magnitude (size) of the green arrows changes, the size of the circled arrows changes accordingly.
Also, the direction of the circled arrow was constant for both top and bottom arrows.
Velocity changes with direction BUT speed does not change with direction, and has a complete meaning with only magnitude.
Thus, the circled vectors represent speed.

how does a meteor transfer energy?
Answer:
Hope this answered your question!~ (Sorry if you get it wrong or I got it wrong-)
Explanation:
When an impact event happens, the enormous kinetic energy of the asteroid or meteorite – a massive body travelling at high speed – is partly transferred to the Earth but largely converted into heat and sound, creating pressure waves travelling radially outwards from its centre, similar to that of an atom bomb.

Why is carbon so important to living things on earth
Answer:
It helps planet earth to survive
Explanation:
Although much less abundant than nitrogen and oxygen in Earth's atmosphere, carbon dioxide is an important constituent of our planet's air. A molecule of carbon dioxide (CO 2) is made up of one carbon atom and two oxygen atoms. Carbon dioxide is an important greenhouse gas that helps to trap heat in our atmosphere.
Two curves on a highway have the same radii. However, one is unbanked and the other is banked at an angle θ. A car can safely travel along the unbanked curve at a maximum speed v0 under conditions when the coefficient of static friction between the tires and the road is 0.563. The banked curve is frictionless, and the car can negotiate it at the same speed v0. Find the angle θ of the banked curve.
Answer:
θ = 29.38°
Explanation:
The centripetal force is given by the formula;
F_c = F_n(sin θ) = mv²/r
Now, the vertical component of the normal force is; F_n(cos θ)
Now, this vertical component is also expressed as; F_n(cos θ) = mg
Thus, the slope is;
F_n(sin θ)/F_n(cos θ) = (mv²/r)/mg
tan θ = v²/rg
v² = rg(tan θ)
The initial speed will be gotten from the relation;
(v_o)² = μ_s(gr)
Plugging rg(tan θ) for (v_o)², we have;
μ_s(gr) = rg(tan θ)
rg will cancel out to give;
μ_s = (tan θ)
Thus, θ = tan^(-1) μ_s
μ_s is coefficient of static friction given as 0.563
θ = tan^(-1) 0.563
θ = 29.38°

A water-skier is pulled behind a boat by a rope that is at an angle of 13° and has a tension of 490 N. The water-skier has a mass of 49 kg.
What are the magnitudes of the x- and y- components of the tension?
What is the normal force acting on the skier?
Answer:
normal force= 480.2 x component=477.4 y component= 110.4
Explanation:
I'm sorry I just did this today in class but i think normal force has to be equal to mg or the mass * gravity of the person and that would be 480.2 newtons. I multiplied 9.8 (gravity) by the mass of 49g
I think for the x and y components you can make a triangle with the angled string and then use sohcahtoa to solve for the tension. I used cos(13) = x/490 to solve for x component and then I used the pythagoran theroem to get the remaining side which would be : a^2 + 477.4^2 = 490^2
hope this can help and that it is correct. good luck
The magnitudes of the x- and y- components of the tension is 477.44N and 110.23N
The normal force acting on the skier is 480.2N
The magnitude of the x- and y- components of the tension is expressed as:
x = Tcos 13°y = T sin 13°Given the following
Tension T = 490N
x = 490 cos13° = 477.44N
y = 490sin13° = 110.23N
Hence the magnitudes of the x- and y- components of the tension is 477.44N and 110.23N
The normal force acting on the skier is equal to the weight.
N = W = mg
N = W = 49 * 9.8
N = W = 480.2N
Hence the normal force acting on the skier is 480.2N
