Consider a block moving in a horizontal circular path on the inner surface of a cone. The normal force on the block is :

A block of mass m is released from rest at a height R above a horizontal surface. The acceleration due to gravity is g. The block slides along the inside of a frictionless circular hoop of radius R. What is the magnitude of the normal force exerted on the block by the hoop when the block has reached the bottom ?

A block of mass 70kg is kept on a rough horizontal surface (mu=0.4) . A person is trying to pull the block by applying a horizontal force, but the block is not moving. The net contact force exerted by the surface on the block is F , then:

Consider a large block placed on a smooth horizontal surface, with a man standing at one end of the block. The man walks to the other end, relative to the block. The distances (absolute) moved by the man and the block are :

A 5 kg block moves in a straight line on a horizontal frictionless surface under the influence of a force that varies with position as shown in the figure. Find the work done by this force as the block moves from the origin to x = 8m.

A block of 200 g mass moves with a uniform speed in a horizontal circular groove, with vertical side walls of radius 20 cm. If the block takes 40 s to complete one round, the normal force by the side walls of the groove is :

A block of mass m is projected on a smooth horizontal circular track with velocity v what is the average normal force exered by the circular walls on the block during motion A to B?
