(17%) Problem 1: A box with a mass m = 96 kilograms is being pulled by a constant force F = 186 newtons at an angle 0 = 35 degrees. The initial speed of the box is zero m/'s. F M X Otheexpertta.co A 33% Part (a) Write an expression for the work done by force F as the block moves a horizontal distance d. A 33% Part (b) How much work, in joules, was done in moving the block 3.1 meters? D A 33% Part (c) What is the speed of the box at when the magnitude of the displacement is d = 3.1 m if the surface is frictionless?(17%) Problem 2: Suppose the ski patrol lowers a rescue sled carrying an injured skier, with a combined mass of 87.6 kg, down a 60.0" slope at constant speed, as shown in the Figure. The coefficient of kinetic friction between the sled and the snow is 0.100. W 60 Othe A 25% Part (a) How much work, in joules, is done by friction as the sled moves 29.4 m along the hill?
