A mass of 5 kg stretches a spring 10 cm. The mass is acted on by an external force of 10 sin( t/2) N(newtons) and moves in a medium that imparts a viscous force of 2 N when the speed of the mass is 4 cm/s. If the mass is set in motion from its equilibrium position with an initial velocity of 3 cm/s, formulate the initial value problem describing the motion of the mass. A)Find the solution of the initial value problem in the above problem. B)Plot the graph of the steady state solution C) Identify the transient and steady -state parts of the solution.
