The box shown in the figure below has mass m = 7.0 kg and slides down a frictionless plane tilted at an angle θ = 25.0° to the horizontal. (a) Determine the acceleration of the block as it slides down the plane. Draw a FBD of the box. (b) If the surface between the box and the plane has a coefficient of kinetic friction = 0.15, find the acceleration of the box down the plane. Draw a FBD of the box. (c) If the box starts from rest 10.0 m up the plane from its base, what will be the box’s speed when it reaches the bottom of the incline?
