A mass weighing 12lb stretches a spring 10in. The mass is attached to a viscous damper with damping constant 3lb⋅s/ft. The mass is pushed upward, contracting the spring a distance of 2in, and then set into motion with a downward velocity of 4in/s. Determine the position u of the mass at any time t. Use 32ft/s2 as the acceleration due to gravity. Pay close attention to the units. u(t)=
Answer :
Given that
mass weight is 12 lb
stretches a spring is 10 in
damping constant 3 lb. s /ft
mass is pushed upward contracting the spring a distance of 2 in
down word velocity of 4 in /s
mass ant time t ,
the acceleration due to gravity is 32 ft/s^2
