The velocity-time graph of a moving particle is shown in the figure. How much force acts on the body?

Answer:

We know that, Force = mass × acceleration From the graph it is clear that as time increases \[(v)=2\text{ }m/s\]Velocity is constant \[\text{(P)}=?\]The body is moving with uniform velocity \[P=mv\]acceleration = 0 \[\therefore \]Force\[=mass\times 0=0\] \[\therefore \]No force is acting on the body.
