A ring of mass M = 90 gram and radius R = 3 meter is kept on a frictionless horizontal surface such that its plane is parallel to horizontal plane. A particle of mass 10 gram is placed in contact with the inner surface of ring as shown figure. An initial velocity v =2^(1/2) m/s is given to the particle along the tangent of the ring. Find the magnitude of the force of interaction in milli newton between them after 1 sec from the start.

A man of mass M =58 kg jumps from an aeroplane as shown in Fig. He sees the hard ground below him and a lake at a distance d = 1 m from the point directly below him. He immediately puts off his jacket (mass m =2 kg) and throws it in a direction directly away from the lake. If he just fails to strike the ground, find the distance (in 101m) he should walk now to pick his jacket. (Neglect air resistance and take the velocity of man at the time of jump with respect to earth zero.)
