A spring with a spring constant of 251.9 N/m is compressed by 0.230 m. Then a steel ball bearing of mass 0.0374 kg is put against the end of the spring, and the spring is released.
What is the speed of the ball bearing right after it loses contact with the spring? (The ball bearing will come off the spring exactly as the spring returns to its equilibrium position. Assume that the mass of the spring can be neglected.)
