1. A mass M is connected to a wall by an ideal spring. The mass is on a frictionless surface. The mass is pushed toward the wall, compressing the spring by a distance X. Use the impulse-momentum theorem to demonstrate that the mass will reach a maximum velocity of X * (K / M)^1/2. 2. J = delta P, P = MV 3. J = delta P Fn * t = MV - 0 -kx * t = MV What is t supposed to be? How can I finish this problem?
