The ballistic pendulum is a simple device to measure projectile velocity v by observing the maximum angle θ to which the box of sand with embedded projectile swings. Calculate the angle θ if the 2‐oz projectile is fired horizontally into the suspended 50‐lb box of sand with a velocity v = 2000 ft/sec. Also find the percentage of energy lost during impact.
