Problem 3: A person pulls a block of ice across a frozen part of a lake. They apply a force to the block that is directed 25° above the horizontal. The block has a mass of 40 kg. The coefficient of kinetic friction between the block and the frozen lake is μk = 0.03. What must be the magnitude of the force applied by the person in order for the block to have a constant velocity?
