A) Calculate the speed of the block right after the collision.

I thought the equation to use was mv of bullet = (M+m)V of block. I came up with 2.67 but the answer is supposed to be 3.6 m/s.

B) As a result of the collision, the spring compresses to a mazimum of 0.20m. Find the spring constant

--The equation to this is 1/2mv^2 = 1/2kx^2 right? I can't get the answer to this question without the answer to part A.

C) Find the inelastic energy loss during the collision
