2.Motion in Straight Line

medium

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).

Option A

Option B

Option C

Option D

Solution

If gravity effect is neglected, then ball will turn back with same speed once bat hit it. Before ball 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.

A particle is moving with speed $v= b\sqrt x$ along positive $x-$ axis. Calculate the speed of the particle at time $t = \tau$ (assume that the particle is at origin at $t = 0$ ).
