A trolley containing water has total mass `1000 kg`. Now water starts coming out of the trolley at the rate of `10 kg//s` from below it. Find the velocity of the trolley after 50 sec,If the initial speed is `10 m//s` on the horizontal frictionless road.

If a trolley starts from rest with an accerelaton of 2m/s^(2) , the velocity of the body after 4 s would be

48.A block of mass 5kg is at rest on a smooth horizontal surface Water coming out of a pipe horizontally at the rate of 2kg/sec ,hits the block with a velocity of 6m/sec.The initial acceleration of the block is

A trolley of mass 360 kg is lying on a horizontal frictionless surface. A mas of mass 40 kg runs with uniform speed on the trolley by a distance of 2m in 0.5 second. What is the velocity of the trolley relative to earth ?

A constant force F is applied on a trolley of initial mass m_0 kept over a smooth surface. Sand is poured gently over the trolley at a constant rate of (mu) kg//s . Afer time t, find (a) mass of the trolley (with sand) (b) net force on the trolley (c) velocity of trolley

A trolley of mass 200 kg moves with a uniform speed of 36 km/ h on a frictionless track. A child of mass 20 kg runs on the trolley from one end to the other (10 m away) with a speed of 4 m s^-1 relative to the trolley in a direction opposite to the its motion, and jumps out of the trolley. What is the final speed of the trolley? How much has the trolley moved from the time the child begins to run?
