A block M = 1.25 kg is pulled up along an inclined plane by a constant force F which is parallel to the incline as shown. The coefficient of kinetic friction between the block and the plane surface µk=0.35. The block starts from rest at the bottom. The block’s speed when it reaches the top is 0.511 m/s. How much is F?
