Do it step by step please
A vertical spring with a fixed upper end and constant 1.6 N / m has a 400 g object suspended at its lower end. An external force acts numerically on the weight, in newtons equal to F (t) = 2 sin (2t), with a positive downward direction. Initially the weight is 15 cm below the equilibrium position and is thrown with an initial upward velocity of 1.2 m / s. If the damping force is negligible: (a) Write the differential equation associated with the problem and its initial conditions. (b) Determine the position of the object at any time t. (c) Indicate whether this system enters mechanical resonance. Justify.
