A force in the negative direction of an x axis is applied for 25 ms to a 0.70 kg ball initially moving at 13 m/s in the positive direction of the axis. The force varies in magnitude, and the impulse has magnitude 29.2 N s. (a) What is the ball’s velocity (including sign for direction) just after the force is applied? (b) What is the average magnitude of the force on the ball? (a) Number Units (b) Number Units
