Problem: You can model a golf club hitting a golf ball as a collision between two objects: the moving head of the gold club and the stationary ball. We will ignore the shaft of the gold club and the golfer in this problem. A gold ball has a mass of 46 g. A typical golf club head would have a mass of 200 g and could be swung so that it has a speed of 35 m/s right before it hits the ball. The gold ball then takes some of the club's momentum and leaves the tee at 55 m/s. 1. In order to use conservation of momentum, we must first identify a system for which momentum is conserved. What is the system for this problem? 2. What is the momentum of this system? 3. What is the speed of the golf club head after the collision? 4. Sketch a graph of the impact force on the golf ball versus time. This is not information you are given in the problem, but reading the book chapter will probably give you an idea of the right graph shape. I'm only looking for the right shape, not any values. 5. Using a collision time of 0.0005 seconds, determine the impulse imparted to the ball by the golf club head.
