1. The ballistic pendulum is a simple device to measure projectile velocity v by observing the maximum angle 8 to which the box of sand with embedded projectile swings. Calculate the angle 8 if the 60 g. projectile is fired horizontally in to the suspended 20 kg box of sand with a velocity of 600 m/s. Also, calculate the percent energy lost during impact. Answer: (a) 8 20.7° (b) energy lost during impact = 99.8% 2m

Transcribed Image Text:1. The ballistic pendulum is a simple device to measure projectile velocity v by observing the
maximum angle 8 to which the box of sand with embedded projectile swings. Calculate
the angle 8 if the 60 g. projectile is fired horizontally in to the suspended 20 kg box of
sand with a velocity of 600 m/s. Also, calculate the percent energy lost during impact.
Answer: (a) 8 = 20.7° (b) energy lost during impact = 99.8%
