Suppose a spring with spring constant

k=1 supports a mass of 1kg and is subject to a driving force f(t)=sin2t. The mass is initially at rest at its equilibrium point. At time t=2, the mass is hit with a sharp upward blow, so that the force of the blow is (t2). Set up and solve (using Laplace transforms) an initial-value problem modelling this situation.
