A child is sitting on a sled and together they have a mass of 25.0 kg. The sled is being pulled by a rope which is angled 15 degrees from the slope. The sled is being pulled at a constant speed of 1.22 m/s up a 25.0 degrees hill that is 65.0 meters long. If the coefficient of friction between the sled and the snow is 0.180, what force is being used to pull the sled?

A girl is sitting in a sled sliding horizontally along some snow (there is friction present). The mass of the girl is 36.8 kg and the mass of the sled is 6.6 kg. The force of friction acting on the sled as it slides is -118 N. If the sled was initially moving at 14.3 m/s at t=0, how far will it slide before the sled stops?

A 33.5 lb child holding a 10.8 kg sled starts running towards a downward slope. The child then jumps on the sled with an initial speed of 0.640 m/s and then slides down the frictionless slope. The child with sled has a speed of 5.25 m/s at the bottom of the hill. a) What is the height of the hill? b) What is the gravitational potential energy of the child/sled at bottom of the hill?

A heavy sled is being pulled by two people as shown in the figure. The coefficient of static friction between the sled and the ground is μs = 0.619, and the kinetic friction coefficient is μk = 0.459. The combined mass of the sled and its load is m = 366 kg. The ropes are separated by an angle φ = 22°, and they make an angle θ = 31.8° with the horizontal. Assuming both ropes pull equally hard, what...
