Ballistic Pendulum To apply conservation of energy and momentum. As shown, an object of mass m is fired with an initial speed v0 at a ballistic pendulum’s bob. The bob has mass M and is suspended by a massless rod of length L. After the collision, the pendulum’s bob and object stick together and swing to a maximum angular displacement θ. Find an expression for v0, the initial speed of the object fired. Express your answer in terms of some or all of the variables m, M, L, and θ and g, the acceleration due to gravity.

A 4000lb wrecking ball hangs from a 20ft cable of density 10lb/ft attached to a crane. Calculate the work done if the crane lifts the ball from the ground level to 20ft in the air by drawing in the cable.
Students are given two spherical balls made of different materials, but of identical mass and diameter to experiment with. Each ball is dropped from an initial height, h0. The “sad ball” comes to rest without visibly bouncing when it strikes the tabletop. The “happy ball” bounces up to a final height h, where h< h0 A fellow student wants to use one of the balls in a carnival game where cups are knocked over by a thrown ball. Which ball should they use, happy or sad? Why?
An object of mass M is attached to a string. The length of the string is r and has no mass. The objects moves in a vertical circle counterclockwise as shown. When the ball is at point F, the string is horizontal. Point E is at the bottom of the circle and point D is at the top of the circle. Air resistance is negligible. Express all algebraic answers in terms of the given quantities and fundamental constants. Suppose that the string breaks at the instant the ball is at point F. Describe the motion of the ball immediately after the string breaks.
