A 50.0-kg boy runs at a speed of 10.0 m/s and jumps onto a cart as shown in the figure. The cart is initially at rest. If the speed of the cart with the boy on it is 2.50 m/s, what is the mass of the cart?

A force F is applied to the initially, stationary cart. The variation of force with time is shown in the figure. The speed of cart at t = 5 s is

The graph below shows the variation of a force (F) with time (t) on a body which is moving in a straight line. Dependence of force on time is F prop t^(n) . Initially body is rest. If the speed of the object is 2m//s at 3s , the speed at 4s will be approximately (m/s)

A block B is placed over a cart which in turn lies over a smooth horizontal floor. Block A and Block C are connected to block B with light inextensible strings passing over light frictionless pulleys fixed to the cart as shown. Initially the blocks and the cart are at rest. All the three blocks have mass m and the cart has mass M(M=3m) . Now a constant horizontal force of magnitude F is applied to block A towards right. Q. Let the coefficient of friction between block B and cart is mu(mugt0) and friction is absent everywhere else. Then the maximum value of force F applied to block A such that there is no relative acceleration between block B and cart is

The force F = 2t^(2) is applied on the 2 kg block. Then find out the work done by this force in 2sec. Initially at time t = 0, block is at rest.

A block B is placed over a cart which in turn lies over a smooth horizontal floor. Block A and Block C are connected to block B with light inextensible strings passing over light frictionless pulleys fixed to the cart as shown. Initially the blocks and the cart are at rest. All the three blocks have mass m and the cart has mass M(M=3m) . Now a constant horizontal force of magnitude F is applied to block A towards right. Assuming friction to be absent everywhere, the magnitude of acceleration of cart at the shoen instant is

A man of mass 80 kg is riding on a small cart of mass 40 kg which is rolling along a level floor at a speed 2 m/s . He is running on the cart , so that his velocity relative to the cart is 3 m/s in the direction opposite to the motion of cart . What is the speed of the centre of the mass of the system ?

A cart of mass 150 kg is pulled horizontally on a frictionless surface with face 10 N. If 100 g/s sand is being dropped in the cart verticlly then find the speed of the system when cart has 100 kg snad in it.

A child of mass 4 kg jumps from cart B to cart A and then immediately back to cart B . The mass of each cart is 20 kg and they are initially at rest. In both the cases the child jumps at 6 m//s relative to the cart. If the cart moves along the same line with negligible friction with the final velocities of V_(B) and V_(A) , respectively, find the ratio of 6V_(B) and 5v_(A) .
