The graph shows the variation with time $t$ of velocity $v$ of an object moving along a straight line. $a-t$ graph will be
A body under the action of several forces will have zero acceleration
Draw $x \to t$ graph for positive acceleration.
A car moving with a speed of $40\, km/h$ can be stopped by applying brakes after atleast $2\, m$. If the same car is moving with a speed of $80 \,km/h$, what is the minimum stopping distance............$m$
Which of the following speed-time $(v-t)$ graphs is physically not possible?
