Unformatted text preview: F ( t ) = 2 sin 3t lb. (Given that g = 32ft/sec 2 .) Let u ( t ) denote the displacement of the mass from its equilibrium position at time t , measured positive downward. Find a differential equation for u . 2. (5 points) Consider the springmass system whose motion is governed by y 00 + 2y + y = 0. Determine all values of the positive constant for which the system is (a) underdamped, (b) critically damped, and (c) overdamped....
