Two block of same mass m undergo headon collision as shown. E is the coefficient of restitution. Choose the correct statement(s) :

Options

A. If e = 1, just after collision KE of right block is `(1)/(2)mv^(2)`.
B. If e = 0, loss in KE is `(1)/(2)((mv^(2))/(2))`.
C. If e = `(1)/(2)`, loss in KE = `(3)/(16)mv^(2)`.
D. No impulsive force acts on left block during collision.

Answer

A, B, D

Explanation

With respect to box, psudo force = mg act upwards. So `F_("net")=0`
