A collar B of mass `2kg` is constrained to move along a horizontal smooth and fixed circular track of radius `5m`. The spring lying in the plane of the circular track and having spring constant `200Nm^-1` is underformed when the collar is at A. If the collar starts from rest at B, the normal reaction exerted by the track on the collar when it passes through A is

A block of mass m is lying at rest at point P of a wedge having a smooth semi-circular track of radius R. What should be the minimum value of a_0 so that the mass can just reach point Q

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?

A small collar of mass m = 100 g slides over the surface of a horizontal circular rod of radius R = 0.3 m. The coefficient of friction between the rod and the collar is mu = 0.8 . Find the angle made with vertical by the force applied by the rod on the collar when speed of the collar is V = 2 m/s.

A small collar of mass m is given an intial velocity of magnitude v_(0) on the horizontal circular track fabricated from a slender rod. If the coefficient of kinetic friction is mu_(K) , determine the distance travelled before the collar comes to rest. (Recognize that the friction force depends on the net normal force).

Figure shows a smooth curved track terminating in a smooth horizontal part. A spring of sprng constant 400 N/m is asttached at one end ot a wedge fixed rigidly with the horizontal part. A 40 g mas is released from rest at a height of 4.9 m n the curved track. Find the maximumcompression of the spring.

A small block of mass m, can move without friction on the outside of a fixed vertical circular track of radiusR. The block is attached to a spring of natural length R//2 and spring constant K. The other end of spring is connected to a point at height R//2 directly above the centre of track. If the block is released from rest when the spring is in horizontal state (see figure) then at that moment,

Figure shows a smooth vertical circular track AB of radius R. A block slides along the surface AB when it is given a velocity equal to sqrt(6gR) at point A. The ratio of the force exerted by the track on the block at point A to that at point B is

A small block of mass m, can move without friction on the outside of a fixed vertical circular track of radiusR. The block is attached to a spring of natural length R//2 and spring constant K. The other end of spring is connected to a point at height R//2 directly above the centre of track. If the complete stup is in a gravity free space, then the minimum speed (v_(0)) required at the highest point A to just reach the lowest point is
