5) A 2 kg mass moving with a velocity of 7 m/s collides elastically with a 4 kg mass moving in the opposite direction at 4 m/s. The 2 kg mass reverses direction after the collision and has new velocity of 3 m/s. What is the velocity of the 4 kg mass? = 2 kg =.7m/s = 4 kg = 4m/s = 3m/s V = ? fe 6) A mass of 3 kg is attached to a massless spring with a force constant 500 N/m. The mass rests on a horizontal frictionless surface. The system is compressed a distance of 30 cm from the springs initial position and then released. The momentum of the mass when the spring passes its equilibrium position is? зку = 500 N/m - 30 cm = ?
