A horse plls a sleigh via a rope that makes an angle of 15 degrees above the horizontal. The sleigh has a mass of 300.0kg and the kinetic coefficent of friction between the sleigh and the snow is 0.15. If the sleigh moves at constatn velocity, how much work does the horse do as she drags the sleigh for 5.0 km? How much work is doen by friction? Hiow much work will be done by friction if the sleigh is dragged a distance of 1.0km, turned around, and then dragged 1.0 km in the opposite direction? Finally, if the sleigh is accelerated at 2.0 m/s^2, what is the tension in the rope and the work done on the sleigh by the horse over a distanc eof 0.1km? I am not sure exactly where and how to begin!
