Suggest a suitable physical situation for each of the following graphs

Asked by Abhisek | 1 year ago |  88

##### Solution :-

(a)The graph is similar to kicking a ball and then it hits the wall and rebounds with a reduced speed. The ball then moves in the opposite direction and hits the opposite wall that stops the ball.

(b) The graph is showing a continuous change in the velocity of the object and at some instant it losses some velocity. Therefore, it may represent a situation where a ball falls on the ground from a certain height and rebounds with a reduced speed.

(c) A cricket ball moving with a uniform speed hit by a bat for a very short time interval.
