2. In a “ballistic pendulum,” the bullet is fired at a massive pendulum bob that is hanging straight downward at rest. The bullet embeds itself in the bob, and the bob+bullet together swing up to some maximum height before pausing to swing back downward.

a.) If the bullet has a mass of 30. g, the bob’s mass is 5.0 kg, and the bob+bullet reaches a final height of 50. cm after impact, what is the speed of the bullet just before impact? Show work completely.

b.) If the length of the pendulum arm is 1.2 m, what maximum angle of displacement does the pendulum arm reach? Show work. Include a diagram of the triangle, clearly showing the angle in question.

a ballistic pendulum is a device used to measure the speed of a bullet. A bullet of mass m = 50g is fired at a block of wood (mass m =750g) hanging from a string. The bullet embeds itself in the block, and causes the combined block plus bullet system to swing up a height h=0.45m. What is the initial speed of the bullet before it hits the block?
