The free‑body diagram shown represents a block of weight \(W = 200\) N resting on a smooth inclined plane that makes an angle of \(30^{\circ}\) with the horizontal. A horizontal push of magnitude \(P = 50\) N is applied to the block as indicated. The coefficient of kinetic friction between the block and the plane is \(\mu_k = 0.20\). Assuming the block moves down the plane, calculate its acceleration (in m s\(^{-2}\)).
