WebSep 7, 2024 · A 1-kg mass stretches a spring 20 cm. The system is attached to a dashpot that imparts a damping force equal to 14 times the instantaneous velocity of the mass. Find the equation of motion if the mass is released from equilibrium with an upward velocity of 3 m/sec. Solution. We have \(mg=1(9.8)=0.2k\), so \(k=49.\)
