In an Inelastic Collision , the momentum of system is conserved .
In the question ,
it is asked about what happens in inelastic collision .
The Inelastic collision is defined as a collision in which there is a loss of kinetic energy. While the momentum of system is conserved in an inelastic collision, kinetic energy is not.
That's because some kinetic energy gets transferred to something else like ⇒ thermal energy, sound energy, or material deformation .
For Example : Let the two similar trolleys are traveling towards each other and if they collide,
but the trolleys are equipped with magnetic couplers they join together in the collision and behave like a one connected mass. This collision is perfectly inelastic .
Therefore , the details about Inelastic Collision is explained above .

Answer:
t=0.704s
Explanation:
A child is running his 46.1 g toy car down a ramp. The ramp is 1.73 m long and forms a 40.5° angle with the flat ground. How long will it take the car to reach the bottom of the ramp if there is no friction?
from newton equation of motion , we look for the y component of the speed and look for the x component of the speed. we can then find the resultant of the speed
Vy^2=0+2*9.8*1.73sin40.5
Vy^2=22.021
Vy=4.69m/s
Vx^2=u^2+2*9.81*cos40.5
Vy^2=25.81
Vy=5.08m/s
V=(Vy^2+Vx^2)^0.5
V=47.71^0.5
V=6.9m/s
from newtons equation of motion we know that force applied is directly proportional to the rate of change in momentum on a body.
f=force applied
v=velocity final
u=initial velocity
m=mass of the toy, 0.046
f=ma
f=m(v-u)/t
v=u+at
6.9=0+9.8t
t=6.9/9.81
t=0.704s

Answer:
1. s
2. m
3. start m/s
4. end m/s
5. m/s^2
Explanation:
1. t is the suffix for the time and it is related to seconds [s]
2. d is the suffix for distance and it is related to meters [m]
3. Vi is the suffix for the initial velocity and it is related to meters per second [m/s]
4. Vf is the suffix for the final velocity and it is related to meters per second [m/s]
5. a is the suffix for the acceleration and it is related to meters per squared second [m/s^2]
Answer:
(d)
Explanation:
because dU = Q -W so ,that the option d(D) is correct
