A rectangular block is mobing along a frictionless path, when it encounters the circular loop as shown. The block passes points `1,2,3,4,` before ret runing to the horizontal tracks. At point 3

A block of mss m is placed on a level frictionless table. The block is attached to a horizontally aligned spring fixed with its other end and is vibrating in a horizontal with the pariod T . Suddenly at the instant of time when the spring comes to the position of euilibrium and becomes unstretched the block disconnects form the spring and continues sliding across the frictionless surface away from the until it encounters loop of radius R . What must be the amplitude of vibrations of the block s on the spring in order for the block to complets one loop without falling down?

A cube of mass M starts of rest from point 1 at a height 4R, where R is the radius of the circular track. The cube slides down the frictionless track and around the loop. The force which the track exerts on the cube at point 2 is :

As shown in figure AB represents an infinite wall tangential to a horizontal semi circular track. O is a point source of light on the ground at the centre of the circle. A block moves along the circular track with speed v starting from the point where the wall touches the circle. If the velocity and acceleration of shadow along the length of the wall is respectively 'V' and 'a' then,

A block of mass m_(1) rests on a horizontal table. A string tied to the block is passed on a frictionless pulley fixed at the end of the table and to the other end of string is hung another block of mass m_(2) . The acceleration of the system is
