1. A ball of mass 106.9 g is placed on a vertical spring of spring constant 200 N/m, and the spring is
compressed by 50 cm from its equilibrium length. The ball is released from rest. How high does it
rise above its starting point on the compressed spring? Express your answer in meters and round to 1 decimal place ex. 10.7 Don’t put units in the answer box.
Hint: The ball starts from rest and stops for an instant at the max height. So the change in kinetic energy = 0. Use the energy equation to solve this problem. Neglect air resistance and use SI units.
