9/11 Newton's Cradle Analysis

Your Newton's Cradle should be built. Determine experimentally the period of one swing of one ball on your Newton's cradle. Use this, and the formula for a pendulum, to calculate the expected length of the pendulum. Compare this to the measured length of the string and the ball. Determine the change in x the far ball goes through if it is hit with a single ball. Do this for a ball that is lifted to h1 and h2. Use Es= 1/2k(change in x)2 to calculate the k of the ball, which is acting as a spring. Remember, in theory, Es should be equal to PE of the ball (m(ball)*accel(g)*height(above ground). Write up the results, and take a picture of your Newton's cradle. Submit both to me via email.
