4 Impulse-Momentum Theorem square6 What is this theorem? square6 Average force
5 Example – Momentum and Impulse 1. A 50-g golf ball is struck with a club as shown. The force on the ball varies from zero when contact is made up to some maximum value (when the ball is deformed) and then back to zero when the ball leaves the club. The force- time graph is also shown. Assume the ball leaves the club face with a velocity of +44m/s 1. Estimate the size and direction of the impulse due to the collision. 2. Estimate the duration of the collision and the average force on the ball.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
