In a ballistic pendulum, a bullet of mass m = 5.50 g is fired with an initial speed v0 = 550 m/s at the bob of a pendulum. The bob has mass M = 2.00 kg, and suspended by a rod of negligible mass. After the collision, the bullet and bob stick together and swing through an arc, eventually gaining a height h. (a) Please find the h. (b) Please find the kinetic energy of the system before the collision and after the collision. (Hint: Use momentum conservation law for the collision process, and then use energy conservation law for the swing process)

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?
