The speed -time graph of the ball in the above situation is.

A

.

B

.

C

.

D

.

Text Solution

Verified by Experts

The correct Answer is:
B
Speed can never be negative. In every collision speed remains half. Motion is accelerated, then retarded, then accelerated and so on. Hence the correct graph is (b).

A ball is thrown vertically upwards. Which of the following plots represent the speed graph of the ball during its flight if the air resistence is not ignored?

Graphs are very useful to represent a physical situation. Various quantities can be easily represented on graphs and other quantites can be determined from the graph. For example the slope of velocity-time graph represents instantaneous acceleration. For a motion with constant acceleration slope of velocity-time graph is constant. If acceleration is changing with time, slope with change and thus velocity-time graph will be a non-linear curve. Further the area of velocity-time graph gives displacement. For the above situation let t_(1) be the time of accelerated motion and t_(2) be the time or retarded motion, then the correct relation is
