Physics ( Damped Oscillations )
posted by Ayman .
A vertical spring with a spring constant of 2.04 N/m has a 0.32-kg mass attached to it, and the mass moves in a medium with a damping constant of 0.025 kg/s. The mass is released from rest at a position 5.6 cm from the equilibrium position. How long will it take for the amplitude to decrease to 2.5 cm?
