The acceleration versus time graph of a particle is shown in the figure. The respective `v-t` graph of the particle is .
.

Options

A. .
B. .
C. .
D. .

Answer

A

Explanation

From `0` to `t_(1)`. Acceleration is increasing linearly with time, hence, `v-t` graph should be parabolec upwards.
From `t_(1`) to `t_(2)` acceleration is dereasing linearly with time, hence, the `v-t` graph should be parabolic downwards.
