A 0.750kg block of wood is attatched to a spring with k = 300N/m. A 0.0030kg bullet is fired into the block, and the spring is compressed 0.102m.
Calculate the velocity of the bullet before the collision.
Is this elastic or inelastic?
How do you do it?
The Attempt at a Solution
I attempted using conservation of momentum, but no v1(prime), v2, v2(prime).
I hesitated to use conservation of energy.
