1.	A ball of mass 0.2 kg is thrown against the wall . the ball strikes the wall normally with velocity of 30m/sand rebounds with velocity of 20m/s. calculate the impulse of the force exerted by the ball on the wall
Answer» *m = 0.2 kg* *u = 30 m/s* *v = 20 m/s* *impulse = change in the MOMENTUM* *final momentum - initial momentum* *mv - mu* *m ( v - u )* **=> 0.2 (-20 -30 )* = -10 Ns**
