A uniform rod of mass m and length l is struck at an end by a force F perpendicular to the rod for a short time interval t. Calculate the angular momentum of the rod about the centre of mass after the force has stopped to act. Assume that t is so small that the rod does not appreciably change its direction while the force acts.

A uniform rod of mass m and length l is struck at an end by a force F perpendicular to the rod for a short time interval t. Calculate a. the speed of the centre of mass ,b. the angular speed of the rod about centre of mass, c. the kinetic energy of the rod and d. the angular moment of the rod about the centre of mass after the force has stopped to act. Assume that t is so small that the rod does not apreciably change its direction while the force acts.

A unidirectional force F varying with time t as shown in the Fig. acts on a body initially at rest for a short duration 2T . Then the velocity acquired by the body is

A particle of mass m is tied to light string and rotated with a speed v along a circular path of radius r. If T=tension in the string and mg= gravitational force on the particle then actual forces acting on the particle are

A unidirectional force F varying with time t as shown in the figure acts for a short duration 2T on a particle which is initially at rest. Then the velocity acquired by the body is:
