## Question ID - 101224 :- Two identical balls, each of mass , are tied with a string and kept on a frictionless surface. Initially, the string is slack. They are given velocities  and  in the same direction. Collision between the balls is perfectly elastic After the first collision, what is the total loss in kinetic energy of the balls? a) b) c) d) Zero

 (d) Since the collision is elastic, there is no loss in KE

The following problemsillustrate the effect of a time–dependent force of a large average magnitude which acts on a moving object only for a short duration. Such forces are called ‘impulsive’ forces. According to the impulse-momentum theorem, impulse delivered to a body is equal to the change of linear momentum of the body

A ball of mass 250 g is thrown with a speed of 30 m/s. The ball strikes a bat and it is hit straight back along the same line at a speed of 50 m/s. Variation of the interaction force, as long as the ball remains in contact with the bat, is as shown in Fig.
