A football punter accelerates a 0.54 kg foot-

ball from rest to a speed of 8.7 m/s in 0.24
s.
What constant force does the punter exert
on the ball?
Answer in units of N

1 answer

Impulse = Force * time = Momentum change
= Mass * (velocity change)

Solve for the force. The force does not have to be constant. I can be a time averaged force during contact
