Part A = ((m+M)/m)(sqrt(2gL(1-cos(θ))))

Part B = 0.852

In a ballistic pendulum an object of mass m is fired with an initial speed v_{0} at a pendulum bob.

Find an expression for v_{0}, the initial speed of the fired object.

An experiment is done to compare the initial speed of bullets fired from different handguns: find the ratio of the initial speed of the 9 mm bullet to the speed of the .44-caliber bullet, v_{0,9}/v_{0,44}

Part A = when the pendulum’s potential energy is a minimum

The speed of a pendulum is greatest
