The figure shows a velocity-time graph of a particle moving along a straight line The total distance travelled by the particle is ........ $m$
$66.6$
$51.6 $
$0$
$36.6$
$v-t$ graph of an object of mass $1\,\, kg$ is shown
A flag is mounted on a car moving due North with velocity of $20 \,\,km/hr$ Strong winds are blowing due East with velocity of $20\,\,km/hr$. The flag will point in direction
The position vector of a particle changes with time according to the relation $\vec r\left( t \right) = 15{t^2}\hat i + \left( {4 - 20{t^2}} \right)\hat j$. What is the magnitude of the acceleration at $t = 1$ ?
Acceleration versus velocity graph of a particle moving in a straight line starting from rest is as shown in figure. The corresponding velocity-time graph would be
