(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A ball of mass 1.5 kg is traveling downward at a speed of 10 m/s. It comes to rest in your hand in .25 s. What is the net impulse exerted on the ball? What is the average force exerted by the hand on the ball (Don't forget the gravitational force.)

2. Relevant equations

J = mv_{f}-mv_{i}

J = F[tex]\Delta[/tex]t

3. The attempt at a solution

I figured out that the impulse is 15 kg m/s from the first equation. I thought that I had figured out the force exerted by the hand on the ball to be 60 N but now I'm not sure what it means by gravitational force. How does this affect the force exerted by the hand on the ball?
