Lab 14 Collisions In this activity you will investigate impulse-momentum for a collision. First consider a foam ball colliding with a wall. 1. When will the magnitude of the force on the ball be a maximum? When the ball first starts to compress? While it is compressing? When it has a maximum compression? Explain. 2. Watch the ball collide with a wall several times. Roughly how long does the collision process take? Half a second? Less? Several seconds? 3. Remembering what you observed, attempt a rough sketch ofthe predicted shape of the curve describing the force the wall exerts on a moving object during a collision.

    PRACTICE IT Use the worked example above to help you solve this problem. A golf ball with mass 5.70 x 10 2 kg is struck with a club as shown in the figure above. The force on the ball varies from zero when contact is made up to some maximum value (when the ball is maximally deformed) and then back to zero when the ball leaves the club, as in the graph of force vs. time in the figure below....
