A father pulls his young daughter on a sled, with a constant velocity, a distance of 10.0m. The total mass of the sled and girl is 35kg and the coefficient of kinetic friction between the sled runners and the snow is 0.20. The father's pull makes an angel of the 30 degree with the respect to the horizontal. A). How many mechanical work dose the father do? B). What is the net mechanical work done on the girl and sled? C). how much mechanical work is done by kinetic friction?

A girl is sledding down a slope that is inclined at 30.00 with respect to the horizontal. The wind is aiding the motion by providing a steady force of 105 N that is parallel to the motion of the sled. The combined mass of the girl and the sled is 65.0 kg, and the coefficient of kinetic friction between the snow and the runners of the sled is 0.150. How much time is required for the sled to travel down...
