10 The ballistic pendulum is a simple device to measure projectile velocity

The ballistic pendulum is a simple device to measure projectile velocity v by observing the maximum angle @ to which the box of sand with embedded projectile swings. Calculate the angle O if the 1.9-oz projectile is fired horizontally into the suspended 46-lb box of sand with a velocity v- 1840 ft/sec. Also find the percentage n of energy lost during impact. 4.8' Answers: 9 - 29.4
