đó t là thời gian.
(a) Xác định thứ nguyên của A và B.
(b) Đơn vị SI của các hằng số A và B là gì?
If v(t) is speed measured in meters per second (m/s), and t is time measured in seconds (s), then the constants A and B in
v(t) = At ³ - Bt
must have units of m/s⁴ and m/s², respectively; otherwise, the equation is dimensionally inconsistent.
[m/s] = A [s]³ - B [s]
[m/s] = [m/s⁴] [s]³ - [m/s²] [s]
[m/s] = [m/s] - [m/s]
[m/s] = [m/s]

A 10-cm-long archerfish begins such a leap with its body vertical in the water, using its fins and undulating its body to propel itself sharply upward. Its acceleration steadily decreases as it leaves the water because less of its body and fewer of its fins are in contact with the water.
With what speed does the fish leave the water?
What height above the water does it reach?
Answer:
Explanation:
Velocity will be equal to the area under the curve of the acceleration-time plot.
v = ½(45)(0.075) = 1.6875
v = 1.7 m/s

Answer:
[tex]\boxed {\boxed {\sf 875 \ Joules}}[/tex]
Explanation:
Kinetic energy is the energy an object possesses due to motion. It is calculated using the following formula:
[tex]KE= \frac{1}{2}mv^2[/tex]
The mass of the person is 70 kilograms and they are moving at a speed of 5 meters per second.
m= 70 kg v= 5 m/sSubstitute these values into the formula.
[tex]KE= \frac{1}{2} (70 \ kg )(5 \ m/s)^2[/tex]
Solve the exponent.
(5 m/s)² = 5 m/s * 5 m/s = 25 m²/s²[tex]KE= \frac{1}{2}(70 \ kg)(25 \ m^2/s^2)[/tex]
Multiply the numbers in parentheses.
[tex]KE= \frac{1}{2} (1750 \ kg*m^2/s^2)[/tex]
Multiply by 1/2 or divide by 2.
[tex]KE= 875 \ kg*m^2/s^2[/tex]
Convert the units. 1 kilogram meter squared per second squared is equal to 1 Joule. So, our answer of 875 kg*m²/s² is equal to 875 Joules.
[tex]KE= 875 \ J[/tex]
The person has 875 Joules of kinetic energy.

SI units are used for scientific works. Why?
Answer:
SI units are used for scientific works to bring uniformity in measurements all over the world.
the colour of the shadow of coloured objects is not same as the colour of the objects
When an opaque item absorbs all of the light falling from a light source, no light is reflected, and the thing appears black. The color of an object's shadow is independent of its hue; it can be red, yellow, green, or black.
One of your classmates, in a fit of unrestrained ego, jumps onto a lab table:
a) Draw a qualitative force diagram for the table. Use marks on the vectors to show the balance of forces.
b) Your classmate’s mass is 65 kg and the table weighs 0 N. Calculate the normal force on the table by the floor. Show your work!
c)Find the mass of the table
The equilibrium condition allows finding the results for the forces of the system are
a) The free body diagram is in the attachment
b) The normal force is N = 737 N
c) The mass of the table is 10.2 kg
Newton's second law indicates that the net force is proportional to the product of the mass and the acceleration of the bodies, in the special case that the acceleration is zero, it is called the equilibrium condition
∑ F = 0
Where the bold letters indicate vectors, F is the external forces
a) A free body diagram is a scheme of the forces without the details of the bodies, in the attachmentt we see a free body diagram of the system.
b) The reaction force of the ground is applied in each of the legs of the table, in general this force has the same magnitude in each leg, therefore in Newton's second law we can place it as a single force
N = N₁ + N₂ + N₃ + N₄₄
Let's apply the equilibrium condition
N - [tex]W_m -w_{table}[/tex] = 0
N = [tex]W_m +w_{table}[/tex]
N = [tex]M_m g + w_{table}[/tex]
They indicate the pose of the boy is 65 kg, for the weight of the table of a laboratory table is approximately 100 N
N = 65 9.8 + 100
N = 737 N
c) To calculate the mass of the table we use the relation
W = [tex]m_{table}[/tex] g
[tex]m_{table} = \frac{w_{table}}{g}[/tex]
[tex]m_{tabble}= \frac{100}{9.8}[/tex]
[tex]m_{table}[/tex]e = 10.2 kg
In conclusion using the equilibrium condition we can find the results for the forces are
a) The free body diagram is in the attachment
b) The normal force is N = 737 N
c) The mass of the table is 10.2 kg

Answer:
FalseIt has four compartments just not including all of those
Explanation:
Ruminant stomachs have four compartments: the rumen, the reticulum, the omasum and the abomasum.Anatomy of the ruminant digestive system includes the mouth, tongue, salivary glands (producing saliva for buffering rumen pH), esophagus, four-compartment stomach (rumen, reticulum, omasum, and abomasum), pancreas, gall bladder, small intestine (duodenum, jejunum, and ileum), and large intestine (cecum, colon, and rectum).. The artificial sweetener NutraSweet is a chemical called aspartame (C14H18N2O5). What is (a) its molecular mass (in atomic mass units)? (3) (b) the mass (in kg) of an aspartame molecule?
The molecular mass, in atomic mass unit, of aspartame would be 294 amu while the mass, in kg, of an aspartame molecule would be 0.294 kg
Aspartame has the chemical formula C14H18N2O5
C = 12, H = 1, N = 14, O = 16
(a) Molecular weight = (12x14) + (1x18) + (14x2) + (16x5)
= 168 + 18 + 28 + 80
= 294 amu
(b) Mass of 1 molecule of aspartame = mole x molar mass
= 1 x 294
= 294 g
Converting 294 g to kg = 294/1000
= 0.294 kg

One train (22,680 kg) moving east at 170 km/h collides with a car (1,200 kg) that was moving north at 5 km/h. They get attached to each other, moving in the direction of the train. What is the final velocity of the objects and the type of collision? If the collision happened in 1.2X10-3 seconds, what was the force? How much kinetic energy was lost?
According to the law of collision'
m1u1 + m2u2 = (m1+m2)v
Given the following:
m1 = 22,680kg
u1 =170km/h
m2 = 1200kg
u2 = 5km/hr
Get the final velocity "v"
22680(170) + 1200(5) = (22680 + 1200)v
3855600 + 6000 = 12880v
3,861,600 = 12880v
v = 3,861,600/12,880
v = 229.82km/hr
Hence the final velocity of the objects is 229.82km/hr
Since energy was lost after the collision, the type of collision that occurs is an elastic collision.
According to Newton's second law, the formula for calculating the force is expressed as;
F = ma
F = m(v-u)/t
F = 22680+1200(229.82-175)/t
Ft = 23880(54.82)
F = 1,309,101.6/0.0012
F = 1,090,918,000N
Hence the required force is 1,090,918,000N
KE lost = Kinetic energy after collision - Kinetic energy before collision
Kinetic energy after collision = 1/2 * 12880 * 229.82²
Kinetic energy after collision = 340,142,976.656 Jolues
Kinetic energy before collision = 1/2 * 22680(170)²+ 1/2*1200(5)²
Kinetic energy before collision = 327,726,000 + 15000
Kinetic energy before collision = 327,741,000
Kinetic energy lost = 340,142,976.656 - 327,741,000 = 12,401,976.656Joules

Hi there!
On the object, we know that there are two forces working on the object:
-Force due to gravity (Mg)
-Force due to air resistance
Let the positive direction of the force be downwards (direction of the acceleration)
We can write the summation of forces as:
∑F = Mg - Fa
Plug in values. Let g ≈ 10 m/s²
∑F = 30(10) - 50 = 250N
Find the acceleration using the formula:
∑F = m · a
∑F/m = a
Plug in values:
250/30 = 8.33 m/s²
