A ball impinges directly on a similar ball at rest. If `1/4 ^(th)` of the kinetic energy is lost by the impact, the value of coefficient of restitution is:-

A ball impinges directly on another ball at rest. The first ball is brought to rest by the impact. If half of the kinetic energy is lost by the impact, the value of coefficient of restitution is

A ball collides impinges directly on a similar ball at rest. The first ball is brought to rest after the impact. If half of the kinetic energy is lost by impact, the value of coefficient of restitution ( e) is

A ball collides impinges directly on a similar ball at rest. The first ball is brought to rest after the impact. If half of the kinetic energy is lost by impact, the value of coefficient of restitution ( e) is

A ball collides impinges directly on a similar ball at rest. The first ball is brought to rest after the impact. If half of the kinetic energy is lost by impact, the value of coefficient of restitution ( e) is

A ball collides directly with another ball at rest and is brought to rest by the impact. If half of the initial kinetic energy is lost in the impact, then the coefficient of restitution is
