A particle of mass `m_(1)` collides head on with a stationary particles of mass `m_(2)`. If `(m_(1))/(m_(2))` gte, where e is the coefficient of restitution, then :

A partical of mass m_(1) collides head on with a stationary partical of mass m_(2) . If (m_(1))/(m_(2)) gt e where e is the coefficient of restitution, then :

A particle of mass m, collides with another stationary particle of mass M. If the particle m stops just after collision, then the coefficient of restitution for collision is equal to

A particle of mass m, collides with another stationary particle of mass M. If the particle m stops just after collision, then the coefficient of restitution for collision is equal to

A particle of mass m_(1) moves with speed v and collides head on with a stationary particles of mass m_(2) . The first particle continues to move in the same direction If (m_(1))/(m_(2)) is (e = coefficient of restitution )
