A 0.1 kg block is attached to a spring with a constant 2.5 N/m and oscillates on a frictionless table. Its velocity is 0.2m/s when x=0.05.
1. What is the amplitude of oscillations?
2. What is the ball's maximum acceleration?
3. What is the speed of the ball when x=0.03m?
4. What is the ball's position when the acceleration is maximum?
