A force in the negative direction of an x axis is applied for 22 ms to a 0.53kg ball initially moving at 15 m/s in the positive direction of theaxis. The force varies in magnitude, and the impulse has magnitude27.6 N s.
(a) What is theball's velocity (including sign for direction) just after the forceis applied?
(b) What is theaverage magnitude of the force on the ball?
