A child is sitting at one end of a long trolley moving with a uniform speed `v` on a smooth horizontal track. If the child starts running towards the other end of the trolley with a speed `u` (w.r.t. trolley), the speed of the centre of mass of the system will.

Text Solution

Verified by Experts

No change in speed of system as no external force is working.

A child is standing at one end of a long trolley moving with a speed v on a smooth horizontal track. 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 :

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:

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. The velocity of the man with respect to ground v_(1) will be:

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.

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

A (trolley + child) of total mass 200 kg is moving with a uniform speed of 36 km/h on a frictionless track. The child of mass 20 kg starts running on the trolley from one end to the other (10 m away) with a speed of 10 ms^(–1) relative to the trolley in the direction of the trolley's motion and jumps out of the trolley with the same relative velocity. What is the final speed of the trolley? How much has the trolley moved from the time the child begins to run?
