Work Energy And Power Question 297

Question: A collision occurs between two identical balls of mass m each, moving with velocity μ1andμ2 . If the collision is head on and the energy lost in the collision is ΔE=316(u1u2)2 then the coefficient of restitution is

Options:

A) 0.25

B) 0.75

C) 0.5

D) 0.9

Show Answer

Answer:

Correct Answer: C

Solution:

[c] Energy lost in the collision is ΔE=12mured2(1e2)
316(u1u2)2=12murel2(1e2)e=0.5
