Asled plus passenger with total mass m = 52.3 kg is pulled a distance d = 21.8 m across a horizontal, snow-packed surface for which the coefficient of kinetic friction with the sled is μk = 0.13. the pulling force is constant and makes an angle of φ = 36.7 degrees above horizontal. the sled moves at constant velocity. a) write an expression for the work done by the pulling force in terms of m, g (acceleration due to gravity), φ, μk, and d. b) what is the work done by the pulling force, in joules? c) write an expression for the work done on the sled by friction in terms of m, g (acceleration due to gravity), φ, μk, and d. d) what is the work done on the sled by friction, in joules?
