Part A) You have a ballistic pendulum. The projectile has mass m1 and the pendulum bob has mass m2. The pendulum is of length L. The projectile is launched horizontally with an unknown speed vo. After the collision with the pendulum bob, the projectile bounces straight back with a speed vb. The pendulum swings up to a maximum angle of φ. Find vo.
Part B) For the ballistic pendulum above, calculate how much mechanical energy was converted into heat during the full trajectory.

A ballistic pendulum is a device used to measure the speed of a
projectile of mass m (at point A). The projectile is launched
horizontally into a target of mass M which is suspended like a
pendulum (point b). When the projectile strikes the target it
imbeds. The maximum height reached by the pendulum and projectile
together is then measured (point c).

Part 1.) Suppose that we have a ball of mass m=50.0g and a
pendulum bob of mass M=250.0g attached to a pendulum of length
R=0.60m. If we fire the ball into the pendulum with initial
velocity v=10.0 m/s, and the ball sticks in the pendulum bob, to
what vertical height will ball/pendulum bob combination rise? What
angle does this correspond to?

Revisiting the ballistic pendulum. In lab we used both
conservation of momentum and conservation of energy to relate the
launch speed of a projectile to the maximum height of the swing of
a pendulum. Here we will study the parts of this problem in a bit
more detail.

collision of the projectile and the pendulum, but mechanical energy
is not conserved.
