The motion of a car and the wheel is kinda interesting, actually. If the wheel is turned right, the wheels will turn right. If it's left, the wheels will go left, you get the idea. The car will move that direction if it's in motion, though.
Answer:
In space, rockets zoom around with no air to push against. ... Rockets and engines in space behave according to Isaac Newton's third law of motion: Every action produces an equal and opposite reaction. When a rocket shoots fuel out one end, this propels the rocket forward — no air is required.

How far will a car travel in half an hour at
30 mph?
Answer:
The car will travel the distance of 15 miles
S= D/T
therefore
D=ST
D = Distance
S = Speed (30 mph)
T = Time (0.5 Hours)
D = 30 * 0.5 = 15

According to Newton’s 2nd Law, forces cause acceleration. An object hanging from a rope has several forces acting upon it, yet it is not accelerating. Why is this?
Answer:
Because the rope is stopping the force of gravity from acceleration it.

7. An object with a weight of 19.6 N moves with a constant velocity of 20.0 m/s. A net
force of 6.00 N is applied to the object in the direction of its motion for 4.00 seconds.
What is the final momentum of the object?
Answer:
118.4kgm/s
Explanation:
Given parameters:
Weight of object = 19.6N
mass of object = 19.6/9.8 = 2kg
Constant velocity = 20m/s
Force applied = 6N
Time taken = 4s
Unknown:
Final momentum of the object = ?
Solution:
To solve this problem, we use Newton's second law of motion;
Ft = m (v - u)
F is the force applied
t is the time taken
m is the mass
v is the initial velocity
u is the time taken
Ft = mv - mu
mv is the final momentum;
So;
Final momentum = Ft + mu
Final momentum = (19.6 x 4) + (2 x 20) = 118.4kgm/s

when a material absorbs energy from light the energy causes the material to do what?
Answer:
To change.
Explanation:
The Law of Conservation of energy states that energy cannot be destroyed but can only be transformed or converted from one form to another. For example, light energy to heat energy.
When a material absorbs energy from light the energy causes the material to change.
A 0.015 kg marble sliding to the right at 22.5 m / s on a frictionless surface causes an elastic frontal collision with a 0.018 kg marble moving to the left at 18 m / s. After the collision, the first marble moves to the left at 18 m / s. Find the speed of the second marble after the collision.

A projectile is fired at a velocity of 50 m/s straight into the air. What is the velocity of the projectile when the objects displacement is 16 meters and headed downward?
Answer:
the final velocity of the object is 53.04 m/s.
Explanation:
Given;
initial velocity of the projectile, u = 50 m/s
displacement of the object, d = 16 m
let the final velocity of the object = v
Apply the following kinematic equation to determine the final velocity of the projectile.
v² = u² + 2gd
v² = 50² + (2 x 9.8 x 16)
v² = 2813.6
v = √2813.6
v = 53.04 m/s
Therefore, the final velocity of the object is 53.04 m/s.
HELPPPPP MEEEEE PLEASE I NEED TO SUBMIT IN LESS THAN 10 MINSS
Answer:
X = 2146.05 m
Explanation:
We need to understand first what is the value we need to calculate here. In this case, we want to know how far from the starting point the package should be released. This is the distance.
We also know that the plane is flying a certain height with an specific speed. And the distance we need to calculate is the distance in X with the following expression:
X = Vt (1)
However we do not know the time that this distance is covered. This time can be determined because we know the height of the plain. This time is referred to the time of flight. And the time of flight can be calculated with the following expression:
t = √2h/g (2)
Where g is gravity acceleration which is 9.8 m/s². Replacing the data into the expression we have:
t = √(2*2500)/9.8
t = 22.59 s
Now replacing into (1) we have:
X = 95 * 22.59
X = 2146.05 mThis is the distance where the package should be released.
Hope this helps
An object is experiencing an acceleration of 9.0 m/s? while traveling in a circle at a velocity of
6.2 m/s. What is the radius of its motion?
Answer:
4.27m
Explanation:
Recall that for uniform rotational motion,
the formula for centripetal acceleration is given as
Centripetal acceleration = ( velocity)² / radius
in our case we are given :
Centripetal acceleration = 9.0 m/s²
velocity = 6.2 m/s
substituting these into the formula:
9.0 = 6.2² / radius
radius = 6.2² / 9.0 = 4.27m

In handball, who is the only player allowed in the goalie area?
Answer:
Only the goalie is allowed inside the goal crease. The only exception when another player is allowed in the goal area is when they take off from outside the goal area, and shoots or passes the ball before landing. To avoid interference with other players, the player must then exit the goal area as soon as possible.

An egg is drown at a wall and breaks. A second egg is thrown at the same velocity and collides with a bed sheet. The egg does not break. Why does the egg not break when it hits the sheet?
Answer:
The first egg is thrown at a wall and breaks because it has no time to decelerate and it breaks.
While, when a second egg is thrown at wall with same velocity and collides with a bed sheet, it does not break because it get more time to decelerate or collide with the wall. It reduces the amount of force exerted on the egg and it does not break.

my speed is 13.63.
Answer:
Explanation:
Given parameters:
Time for speed walking = 10min
Speed = 13.63?
Unknown:
Distance you can speed walk = ?
Solution:
To solve this problem, we simply apply the velocity - time equation;
Speed = [tex]\frac{distance}{time}[/tex]
Distance = speed x time
make sure you speed and time are in the same unit
Insert the parameters and solve

Answer:
Follows are the solution to the given question:
Explanation:
For point a:
[tex]T= 2\pi \sqrt{\frac{m}{k}}\\\\k = \frac{4 \pi^2 m}{T^2}\\\\= \frac{4 \times (3.14)^2 \times 3}{2^2}\\\\=29.578 \ \frac{N}{m}\\\\[/tex]
For Point b:
[tex]E=\frac{1}{2} m a^2 w^2\\\\[/tex]
[tex]=\frac{1}{2} \times m \times a^2 \times \frac{4\pi^2}{T^2}\\\\=\frac{1}{2} \times 3 \times (0.15)^2 \times \frac{4\times 3.14^2}{2^2}\\\\=0.332 \ J[/tex]
For Point C:
[tex]V_{max}= a w[/tex]
[tex]= (0.15) \times \frac{2\pi}{T}\\\\= (0.15) \times \frac{2\times 3.14}{2}\\\\=0.471 \frac{m}{s}[/tex]
For point D:
[tex]X= a \sin (wt+ \phi)\\\\0.91=0.15 \sin(\frac{2\pi}{T} \times t+\phi)\\\\0.91=0.15 \sin(\frac{2\times 3.14}{2} \times 0.5+\phi)\\\\0.60 = \sin(3.14 \times 0.5+\phi)\\\\0.60 = \sin(1.57+\phi)\\\\1.57 +\phi =\sin^{-1} 60^{\circ}\\\\1.57 +\phi = 36.86^{\circ}\\\\=35.29^{\circ}\\\\So, X=15 \sin(3.14t+35.29^{\circ}) \ cm[/tex]
