. A box (mass = 100 g) is initially connected to a compressed (x = 80 cm) spring (  = 100 N/m) at point A. It was released and started moving along the horizontal surface (  = 0.2) until it moves up along the inclined surface (  = 0.3). The box then stops at point D alone the incline. Consider that  = 30 m and θ = 30o.
