There is no damping in the system and a forcing function of the form F(t) = 10 cos(4t) is attached to the object. If the object is initially displaced 20 cm downward from its equilibrium position and given a velocity of 10 cm/sec upward, find the displacement, u(t), at any time t. Problem 2 (similar to Ex 6): A 3kg object is attached to a spring and will stretch the spring 392 mm by itself. A damper will exert a force of 60 Newtons when the velocity is 2 m/sec. A forcing function of the form F(t) = 10 cos(4t) is attached to the object. If the object is initially displaced 20 cm downward from its equilibrium position and given a velocity of 10 cm/sec upward, find the displacement, u(t), at any time t. Do each of the problems above.
