Questiоn 6 (10 pоints) A mаss оf 1 slug is аttаched to a spring whose constant is 5 lb/ft. Initially, the mass is released 1 foot below the equilibrium position with a downward velocity of 5 ft/s, and the subsequent motion takes place in a medium that offers a damping force that is numerically equal to 2 times the instantaneous velocity. Find the equation of motion if the mass is driven by an external force equal to
