Let us consider the following example: A cricket bat of mass  M  is suspended, so that it can swing around a pivot at point S (near one end of the handle) in vertical plane. If a ball moving horizontally strikes the bat, at point A with an impulsive force  F  for time  Δt , how much impulse is applied to the pivot by the bat during collision? The ball, on collision with the bat, transfers a momentum  Δ p  to the bat given by, Δ p = F Δ t = F Δ t i where ,  Δ t  is the time the ball remains in contact with the bat. The bat is consequently pushed towards  X-axis . Being pivoted at  S , suppose the bat applies an impulse  Δ p’  on the pivot; pivot in turn applies an impulse  (– Δ p’)  on the bat. The net impulse on the bat gives a translation to the center-of-mass C of the bat: Δ p – Δ p’ = Mvc where  v c  is the velocity acquired by  CM  of t
