- Homework Statement
- A bullet passes through a ballistic block and making an inelastic collision

- Relevant Equations
- Energy equations, parabolic equations(?), momentum equations.

Does anyone know how to solve this problem? I translate the full statement:

A 200g bullet is shot against a ballistic block passing it through and making an inelastic collision. The initial speed of the bullet is 200meters/second, the mass of the block is 3kg and the string that holds the block measures 2 meters. The bullet is at 1m of the floor and travels 5 meters in the horizontal axis.

a) What is the speed of the bullet and the block right after the collision?

b) What is the lost energy in the collision?

c) What is the maximum angle that makes the block ?

I don't require the full answer, just an algebraic proposal is enough

(sorry for my english, I'm not native speaker)

Thank you, Josep!
