Question
5. After a mass weighing 10 pounds is attached to a 5-foot spring,the spring measures 7 feet.
This mass is removed and replaced with another mass that weighs 8pounds. The entire system is
placed in a medium that offers a damping force that is numerically equal to the instantaneous
velocity.
a. Find the equation of motion if the mass is initially released from a point 1/2 foot below
the equilibrium position with a downward velocity of 1 ft/s.
b. Express the equation of motion in the form x(t) = Ae sin[( )t ]
