A 7.0-g bullet is fired into a 1.5-kg ballistic pendulum. The bullet emerges from the block with a speed of 200 m/s, and the block rises to a maximum height of 12 cm. Find the initial speed of the bullet.
Conservation of Momentum
The Attempt at a Solution
I first converted all of my units into SI units. I then went to use the Conservation of Momentum for Glancing Collisions, with X and Y components, but I am confused as to what the components of the bullet are. All I know is that the pendulum rises at some angle to .12 m above it's original position and I'm not sure how to interpret this into an equation. Any assistance will be greatly appreciated.
