The correct statement from the following is
A body having zero velocity will not necessarily have zero acceleration
A body having zero velocity will necessarily have zero acceleration
A body having uniform speed can have only uniform acceleration
A body having non-uniform velocity will have zero acceleration
The distance travelled by a body moving along a line in time $t$ is proportional to $t^3$. The acceleration-time $(a, t)$ graph for the motion of the body will be
What would be the stopping distance if the velocity of vehicle becomes three times ?
The area under acceleration-time graph gives
The acceleration-time graph for a particle moving along $x$-axis is shown in figure. If the initial velocity of particle is $-5 \,m / s$, the velocity at $t=8 \,s$ is ....... $m / s$
A body is moving with a uniform acceleration covers $40\,m$ in the first $4\,s$ and $120\,m$ in next $4\,s.$ Its initial velocity and acceleration are
