Draw a velocity versus time graph of a stone thrown vertically upwards and then coming downwards after attaining the maximum height.

Option A

Option B

Option C

Option D

Solution

When a stone is thrown upward, its velocity is at maximum. The velocity begins to drops as the stone attains height. Once the stone attains the maximum height, velocity becomes zero. After that, stone begins to fall down. At this points, velocity beings to rise. Velocity is at its maximum when the stone hits the ground.
