A body 'x' with a momentum 'p' collides with another identical stationary body 'y' one dimensionally. During the collision 'y' gives an impulse 'J' to the body 'x'. Then the coefficient of restitution is

A body 'x' with a momentum 'p' collides with another identical station

1.	A body 'x' with a momentum 'p' collides with another identical stationary body 'y' one dimensionally. During the collision 'y' gives an impulse 'J' to the body 'x'. Then the coefficient of restitution is
Answer» <P>`(2J)/(p)-1` `(J)/(p)+1` `(J)/(p)-1` `(J)/(2P)-1` Answer :A
