pls explain hw we goot the eqns like e^2h and all in this fig.the fig shows a ball bouncing and eventually coming to rest (note e is coefficient of restitution

Question

anonymous · Answer

The coefficient of restitution for an object bouncing off of a stationary object is defined as$$C_R =e  =  {v \over u}$$ where $v$ is the velocity after impact and $u$ is the velocity before impact. 

From the equations of projectile motion, we can express this as$$C_R = e = \sqrt{ h \over H}$$where $h$ is the bounce height and $H$ is the drop height.
