- Bob is pulling a box of his toys of mass 15.0 kg along a rough horizontal surface for a distance of 6.00 m. The tension force in the rope is 58.0 N and the angle is 30° with respect to the horizontal. The frictional force on the box is 12.0 N. How much work is done on the box by the normal force, in Joule? Use g = 10.0 m/s2. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.A man pulls a 4.6-kg sled 50 meters along an angled hill with a force of 36 N, which elevates the man 28 meters above the bottom of the hill. The man then hops on his sled and slides from rest to the bottom of the hill back along his 50 meter path, during which a 299 N frictional force acts upon his sled. How much work in Joules does the man do against friction in pulling the sled up the hill?A man pushes a 85.9-N crate a distance of 3.7 m up a long frictionless ramp at a constant speed. His pushing force is parallel to the ramp. The ramp makes a 30.0-degree angle with the horizontal. What is the work done by the man in pushing the crate? Give your answer in joules, rounded to one decimal place.
