1. An inventor patents a "golf machine". It consists of a "golf club" which is really a pendulum of length L = 2 (m), with a massles string and a mass M = 30 (kg) on the end. By pulling back on the pendulum until the string makes an angle 0= 10° from the vertical, and then releasing it from rest, the golf club strikes the "golf ball" exactly horizontally. The golf ball is a mass m = that rests on a platform which is h = 20 (cm) above the horizontal ground. Assume that all collisions are elastic and all masses are point masses.

In a ballistic pendulum experiment, a small marble is fired into a cup attached to the end of a pendulum.

1. Physics Problem: The ballistic pendulum is a device used to measure the speed of a projectile, such as a bullet. The projectile, of mass m, is fired into a large block of mass M, which is suspended like a pendulum (see the Figure below). As a result of the collision, the pendulum and projectile together swing up to a maximum height h. Determine the relationship between the initial horizontal speed of the projectile, vo, and the maximum height h. Determine the percentage energy loss in the inelastic collision. 2. The ballistic pendulum device will be demonstrated in class. 3. Fire the ballistic pendulum five times and record the pendulum's maximum height after each round. 4. Remove the pendulum arm from the ballistic pendulum. Mass the pendulum arm and the projectile separately. 5. Determine the average speed and the statistical error (standard deviation).
