4. A pitcher applies an average force of 6.2 N in the forward direction on a baseball for 0.65 seconds. The baseball’s mass is 0.145 kg. and initial velocity is zero. What momentum does the baseball have as it is released by the pitcher? How fast is the baseball going after the impulse? (10 points) What is the momentum?

What is the velocity?

5. The catcher catches the baseball in the problem above. It takes 0.15 seconds to stop the ball. How much average force must the catcher apply during that time interval? (Ignore air resistance.)
