Compute each part of given question:
Question: A spring with spring constant 11N/m hangs from the ceiling. A ball is attached to the spring and allowed to come to rest. It is then pulled down 7.5cm and released. The ball makes 25 oscillations in 20s seconds.
Part A: What is its the mass of the ball?
Part B: What is its maximum speed?
