Q.2.
Answer:- perfectly inelastic collision of xarts with equal masses.
Explanation: - when two objects of equal mass collides directly then they stick each other( perfectly inelastic collision) so the final velocity of both cars is zero.
Q.3.

Elastic collisions: one at rest one moving, two colliding, both initially moving the same direction. Inelastic collisions: one at rest one moving, two colliding, both initially moving the same direction. Perfectly elastic collisions: one at rest one moving, two colliding, both initially moving the same direction. Questions1. Was momentum conserved for all types of collisions you examined in this experiment? If not, explain the cause of losing orgaining momentum.2. Was total velocity conserved for all types of collisions you examined...

2. For an elastic collision, which equation could you use to predict the final velocity of Cart 2, which is initially stationary, given the initial velocity of Cart 1 and the masses of the two carts? Explain and show your calculation. 3. To study collisions, you will use two devices called photogates. How does a photogate work?

Contrast and compare elastic and inelastic collisions.
Question 4 options:
Both elastic and inelastic collisions have conservation of
momentum if there are no outside forces. They are different in that
elastic collisions bounce and inelastic collisions stick, and
kinetic energy is conserved in inelastic collisions.
They are basically the same thing, except the units are
different.
Elastic collisions do not have conservation of momentum and
inelastic collisions have conservation of momentum if there are no
