Objective
To determine the initial speed of an object before it collides with a second object by using energy and momentum and to determine the energy lost in a collision.
Consider a pendulum consisting of a small block of mass M suspended by a thin rod of length L. A small ball of mass m traveling horizontally with initial speed vo strikes the block and becomes imbedded in it. The ball/block combination swing together through a maximum angle θ. Derive an expression for vo in terms of M, L, m, θ, and any appropriate constants. Show and explain all your work.

simple way to measure the speed of a bullet is with a ballistic pendulum, which consists of a wooden block of mass m into which a bullet of mass m, is shot. The block is suspended from two cables, each of length L. Assume that the time the bullet takes to come to rest (that is, the bullet is moving at the same speed as the block) is negligibly Small. The impact of the bullet causes the block and embedded...

A bullet with some mass, m, and initial speed, vi, collides with a wooden block of mass M that is hanging at the end of a light rope. The bullet imbeds itself in the block and the block and bullet swings upwards reaching a maximum height of h above the initial point of the collision. a. A scientist can measure the masses and the height, show that the initial speed can then be calculated from the following equation: vi= (m+M)/m×root...

3. The ballistic pendulum is a device used to measure the speed of a projectile, such as a bullet. The projectile, of mass m, is fired into a large block of mass M, which is suspended like a pendulum. As a result of the collision, the pendulum and projectile together swing up to a maximum height h. Determine the relationship between the initial horizontal speed of the projectile, v, and the maximum heighth
