A child is standing at one end of a long trolley moving with a speed $v$ on a smooth horizontal floor. If the child starts running towards the other end of the trolley with a speed $u$ , the centre of mass of the system (trolley + child) will move with a speed
Which of the following is self-adjusting force?
In the above question the speed of the mass when travelled half the maximum distance is
When $F =2 N$, the frictional force between 5 $kg$ block and ground is $..........\,N$
Two masses of $1\, kg$ and $5\, kg$ are attached to the ends of a massless string passing over a pulley of negligible weight. The pulley itself is attached to a light spring balance as shown in figure. The masses start moving during this interval; the reading of spring balance will be
