(a) A soccer player heads the ball
with an average net force of
21 N [W] for 0.12 s. Draw a
graph of the average net force
on the ball as a function of
time. Assume that Fnetave is
constant during the interaction.
(b) Calculate the impulse provided
to the soccer ball.
(c) The impulse changes the velocity
of the ball from 4.0 m/s [E] to
2.0 m/s [W]. What is the mass
of the ball?
