A ball is thrown vertically upwards. Which of the following plots represents the speed-time graph of the ball during its flight in the air (resistance of air is not ignored)?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
c
Both for upward as well as downward motions velocity is proportional to time because in first case v=-gt or `v prop-t` and in second case v=+gt or `v propt` Thus graphically it is a linear variation but in opposite direction .
