1. The problem statement, all variables and given/known data A block of mass 0.28kg is attached to a spring of spring constant 12N/m on a frictionless track. The block moves in simple harmonic motion with amplitude 0.2m. While passing through the equilibrium point from left to right, the block is struck by a bullet, which stops inside the block. The velocity of the bullet immediately before it strikes the block is 53m/s and the mass of the bullet is 4.4g. How long will it take for the block to reach maximum amplitude [which I calculated to be 0.3246) after the collision? 2. Relevant equations M1V1 + M2V2 = (M1+M2)Vf x = Bsin(wt+alpha) I found Vf = 1.309 m/s 3. The attempt at a solution I think the answer will have to solved using the equation, x = Bsin (wt + alpha), but I don't know what numbers to plug in for those. Any help would be greatly appreciated!
