1.	A cricket ball of mass 100 g moving with a speedof 20 ms^(-1) is brought to restby a player . Find the changein momentum of ball.
Answer» `0.5 Ns ` `-2 Ns ` `-2.5Ns ` ZERO Solution :MASS = 0.1kg intial VELOCITY `mu = 20 ms^(-1)` Final velocity v = 0 change in momentum in impulse= m(v - u) = 0.1 (0-20)= - 2NS
