Ballistic Pendulum Lab

Procedure: Used ballistic pendulum to test the angle the pendulum produced, with this we can conclude the velocity, kinetic energy, momentum, etc.

Data Collected: Trial 1 - 33 degrees Trial 2 - 34.5 degrees Trial 3 - 34 degrees

Average Angle: (33+33.5+34)/3 = 33.8333 degrees d x = 2.63m h= .037m m(block) = 79.5 m(bullet) = 7.6g d y = .87m

Equations Velocity (bullet) = ((mblock +mbullet) √(2gh))/(mbullet) Velocity (bullet) = ((.0795 + .0076) √(2x9.8x.037))/(.0076) = 9.792 m/s

d y = .5at^2 d = (2*(d y)/g) v = (d x)/t

t=.421 sec v = 6.42 m/s

Percent Error = 36.27%
