A uniformly moving cricket ball is turned back by hitting it with a bat for a very short time interval. Show the variation of its acceleration with time (Take acceleration in the backward direction as positive).

Text Solution

Verified by Experts

If gravity effect is neglected, then ball will turn back with same speed once bat hit it. Before bal hit the bat, its acceleration is zero but after striking it will be accelerated by impulsive force of bat.
The variation of acceleration with time is shown in graph.
