A man weighing 60 kg is standing on a trolley weighing 240 kg. The trolley is resting on a frictionless horizonral rails. If the man starts walking on the trolley with a constant speed of 1 ms^(-1) then after 4 second. The displacement of the man relative to the ground is :

A man weighing 80 kg is standing on a trolley weighting 320 kg . The trolley is resting on frictionless horizontal rails. If the man starts walking on the trolley along the rails at speed 1 m//s (w.r.t. to trolley) then after 4 s his displacement relative to the ground will be :

A man weighing 80 kg is standing on a trolley weighing 320 kg . The trolley is resting on frictionless horizontal rails. If the man starts walking on the trolley along the rails at speed 1 m//s (w.r.t. to trolley) then after 4 s his displacement relative to the ground will be :

A man of mass m is standing at one end of of a plank of mass M. The length of the plank is L and it rests on a frictionless horizontal ground. The man walks to the other end of the plank. Find displacement of the plank and man relative to the ground.

The figure shows a man of mass m standing at the end A of a trolley of maas M placed at rest on a smooth horizontal surface. The man starts moving towards the end B with a velocity u_(rel) with respect to the trolley. The length of the trolley is L. As the man walks on the trolley, the centre of mass of the system (man+ trolley) :

The figure shows a man of mass m standing at the end A of a trolley of maas M placed at rest on a smooth horizontal surface. The man starts moving towards the end B with a velocity u_(rel) with respect to the trolley. The length of the trolley is L. When the man starts moving, then the velocity of the trolley v_(2) with respect to ground will be:
