medium

The figure shows the velocity $(v)$ of a particle plotted against time $(t)$

AThe particle changes its direction of motion at some point

BThe acceleration of the particle remains constant

CThe displacement of the particle is zero

DAll of the above

Solution

the particle changes its direction of motion at $t = T$ since the velocity becomes positive from negative. the acceleration of the particle remains constant since the slope is constant throughout the curve. the displacement of the particle is $zero$ because the area under the curve of negative velocity is equal to area under the curve of positive velocity. the initial and final speeds of the particle are the same since speed is the magnitude of velocity.
