A block with mass m = 8.0 kg sits on an inclined plane. The angle of the plane with thehorizontal is θ = 25o. (The figure is not drawn to scale). A force F is applied to the block atan angle φ = 20o, as shown. The coefficient of kinetic friction isµ = 0.25.
(a) What force F is required to pull the block up the incline withacceleration 2.0 m/s2? What is the normal force in this case? [Assume g = 9.8 m/s2.]
