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 taking acceleration in the backward direction as positive.
When the ball is hit by bat its acceleration decreases till its velocity becomes zero, so acceleration is in backward direction which here taken is positive as shown in the graph from A to B part. Now after when the velocity of ball decreased to zero is velocity increases in the forward direction so acceleration in forward direction is negative(here) shown by part BC in graph.
