# Collision: Calculating Force and Velocity

Just before it is struck by a racket, a tennis ball weighing 0.560 N has a velocity of (20.0i-4.0j) m/s. During the 3.00 ms that the racket and ball are in contact, the net force on the ball is constant and equal to (-380i+110j)N. What is the x-component of the impulse of the net force applied to the ball? What is the y-component of the impulse of the net force applied to the ball? What is the x-component of the final velocity of the ball? What is the y-component of the final velocity of the ball?

#### Solution Preview

wt. of tennis ball w = 0.560 N

mass of tennis ball m = 0.56/9.8 kg

velocity of ball u1 = (20.0i-4.0j) m/s

time duration t = 3 *10^(-3) s

Force on ball F = ...

#### Solution Summary

The solution provides step-by-step calculations for finding the y and x components of net force and velocity applied to a ball when it collides with a racket.
