A 15kg block slides up a 30∘ inclined plane at a constant velocity. The coefficient of friction between the block and the plane is μk=0.2. In order for the block to slide up the incline, someone must apply a force to the block. What is the magnitude of the applied force if it points parallel to the incline? What is the magnitude of the applied force if it points horizontally instead?
A 15kg block slides up a 30∘ inclined plane at a constant velocity. The coefficient of friction between the block and the plane is μk=0.2. In order for the block to slide up the incline, someone must apply a force to the block. Part A: What is the magnitude of the applied force if it points parallel to the incline? Part B: What is the magnitude of the applied force if it points horizontally instead?
A block of mass = 50.0 kg is being dragged at a constant velocity across a floor by a strong person pulling it with a rope. The rope makes an angle of 300 with the horizontal. The tension in the rope is 50.0 Newtons. Assume a real floor, with friction. What is the coefficient of kinetic friction between the box and the floor?

(22 POINTS) 3 ) A block with a mass of 20 kg rests on a hill inclined at 30P to the horizontal. The coefficient of static friction is 0.25 and the coefficient of kinetic friction is 0.15. What is the magnitude of a force (Fa), applied parallel to the incline, needed to move the block UP the hill at a constant velocity? Express your answer in Newtons using 3 significant figures.
A 10 kg block is dragged by an applied force of 20N, which makes an angle of 600 with the horizontal. The coefficient of friction of the surface is. The block starts from rest and is pulled a distance of 7m. Calculate the work done by the applied force? Calculate the work done by the force of friction? What is the resultant work done? What is the final velocity of the block? Recall: work done equals change in kinetic...
