A man of mass `m` runs without sliding from rest from one end of a boat of mass `M` and length

A particle of mass m is situated at a distance d from one end of a rod of mass M and length L as shown in diagram. Find the magnitude of the gravitational force between them

A man of mass m walks from end A to the other end B of a boat of mass M and length l. The coefficient of friction between the man and the boat is mu an neglect any resistive force between the boat and the water.

A boy of mass m is standing at one end of a boat of mass M and length l. The boy walks to the other end, the displacement of the

A man of mass m is standing at one end of a trolley of mass M and length L placed at rest on a smooth horizontal surface. The man starts moving towards the other end and covers distance L, then distance moved by man w.r.t ground is

No external force: Stationery mass relative to an inertial frame remains at rest 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.

A man of mass m moves with a constant speed on a plank of mass M and length l kept initially at rest on a frictionless horizontal surface, from one end to the other in time t. The speed of the plank relative to grounud while man is moving, is

A particle of mass m and speed u collides elastically with the end of a uniform rod of mass M and length L as shown. If the particle comes to rest after collision, find m/M

A particle of mass m is released from rest from a point A of a wedge of mass 4m free to slide on a frictionless horizontal plane.The particle slides down the smooth face AB of the wedge.When the velocity of the wedge is 0.2m/s the velocity of the particle in m/s relative to the wedge is
