Two balls A and B moving in the same direction collide. The mass of B is

p

times that of A. Before the collision the velocity of A was

q

times that of B . After the collision A comes to rest. If

e

be the coefficient of restitution then which of the following conclusion/s is/are correct?

Options

A $e=\frac{p+q}{p q-p}$
B $e=\frac{p+q}{p q+p}$
C $p \geq \frac{q}{q-2}$
D $p \geq 1$

Correct answer

D. $p \geq 1$

Step-by-step solution
