If the speed of moving object decreases, then give direction of velocity and acceleration.
Two points move in the same straight line starting at the same moment from the same point in it. The first moves with constant velocity $u$ and the second with constant acceleration $f$. During the time elapses before the second catches, the first greatest distance between the particle is $........$
The velocity of a body depends on time according to the equation $v=\frac{t^2}{10}+20$. The body is undergoing
The acceleration of a train between two stations is shown in the figure. The maximum speed of the train is $............\,m/s$
The displacement $(x)$ of a particle depends on time $t$ as $x=\alpha t^2-\beta t^3$. Choose the incorrect statements from the following.
