Answer Happy

please check forces mass ect.. carefully before answering.also upvote for clear working out.
A load is mounted on a spring with a spring constant of 324 N m-¹ and confined to move only vertically, as shown in Figure 3. The wheels which guide the mass can be considered to be frictionless. The load has a mass, m = 4 kg, which includes a motor causing the mass to be driven by a force, F = 8 sin wt given in newtons. X Figure 3 Schematic of a driven harmonic oscillator. The motion of the motor produces a forcing vibration constrained to act vertically. Long description Write the inhomogeneous differential equation that describes the system above. Solve the equation to find an expression for x in terms of t and w.
