Boxes A and B are sliding to the right across a frictionless table. The hand H is slowing them down. The mass of A is larger than the mass of B. rank in order, from largest to samllest, the horizontal forces on A,B and H.

Two blocks of masses m and M are placed on a horizontal frictionless table connected by light spring as shown in figure. The Mass M is pulled to the right with a force F It the acceleration of mass m is a then the acceleration of M will be .

Three metal blocks A , B and C of masses 10 kg , 20 kg and 30 kg rest on a frictionless table in a line . A is converted to B and B to C by two pieces of string . With the help of a third string attached to C , the system is pulled to the right with a force of 60 N . Find the tensions of the first and second strings .

A block of mass m starts at rest at height on a frictionless inclined plane. The block slides down the plane, travels across a rough horizontal surface with coefficient of kinetic friction mu and compresses a spring with force constant k a distance x before momentarilly coming to rest. Then the spring extends and the block travels back across the rough surface, sliding up the plane. The block travels a total distance d on rough horizontal surface. The correct experssion for the maximum height h' that the block reaches on its return is :
