1.	A ball is dropped from a certain height on a horizontal floor. The coefficient of restitution between the ball and the floor is `(1)/(2)`. The displacement time graph of the ball will be.A. .B. .C. .D. .
Answer» Correct Answer - C The ball will stop after a long time. The final displacement of the ball will be equal to the height. The motion is first accelerated, then retarded, then accelerated and so on. Hence the correct graph is ( c).
