Question: A spring with spring constant 18.0 N/m hangs from the ceiling. A 580 g ball is attached to the spring and allowed to come to rest. It is then pulled down 8.00 cm and released.Find time constant if the ball's amplitude has decreased to 2.20 cm after 51.0 oscillations? Explain your answer.
A 1600 kg submarine rises straight up towards the surface. Seawater exerts both an upward buoyant force of 16430 N on the sub, with a downward resistive force of 1000 N. What is the submarine's acceleration.
