Question

In which type of collision do the two objects always have equal velocity after the collision

a. Perfectly inelastic
b. inelastic
c. No Type of collision
d. Elastic

Answer 1

A option is correct .......

Answer 2

Answer: Option A

Step-by-step explanation: In an elastic collision, the two objects only will have the same velocity after the collision if the had it before.

Now, in an inelastic collision the kinetic energy is not conserved, so there is a chance that the two objects that started with a different velocity end with the same, and that case is called "Perfectly inelastic" it occurs when the maximum kinetic energy is absorbed, and both objects "stick" to each other and move together as one, so the correct option is option A.
