Web(i)Define SI unit of force. (ii)A force of 2 N acting on a body changes its velocity uniformly from 2 m/s to 5 m/s in 10 s. calculate the mass of the body. Answer (i).The SI unit of force is Newton and it is the force that will give a mass of 1 kg an acceleration of 1 meter per second per second. (ii). u= 2 m/s,v=5 m/s ,t=10 sec ,F=2 N Web4. Two objects of masses 100 g and, 200 g are moving along the same line and direction with velocities of 2 m/s and 1 m/s respectively. They collide and after the collision the first object moves at a velocity of 1.67 m/s. Determine the velocity of the second object. Ans. m 1 = 100 g = 0.1 kg. m 2 = 200 g = 0.2 kg.
