Goluk, the Inuit, is pulling a 62 kg sled through the snow on his way home from ice fishing. On the back of the sled is his 50 kg sack of fishing tackle. The coefficient of sliding friction between the sled and the snow is 0.07 and the coefficient of sliding friction between the sled and the sack is 0.10.

A father pulls his child on a sled by pulling on a rope over his
shoulder as shown. Using the coefficient of friction for steel on
ice from table 1, calculate the acceleration of the sled if its
mass plus the child is 22 kg, assuming the sled is already in
motion.

1) Shayla is sliding in a sled from a top of a 5-m-high snow hill ( starting from rest.) At the bottom of the hill, her sled hits Tom, who falls into the sled. Toms's mass is the same as Shayla's and her sled altogether. What is the speed of the sled after Tom fell in? Neglect friction w/ snow. 2) You are standing by a smooth frozen lake, and longing to propel a snowball over the lake. In which...
Josh starts his sled at the top of a 2.0 m-high hill that has a constant slope of 25 degrees
Josh starts his sled at the top of a 2.0 m-high hill that has a constant slope of 25 degrees . After reaching the bottom, he slides across a horizontal patch of snow. The hill is frictionless, but the coefficient of kinetic friction between his sled and the snow is 0.07.

An Eskimo returning from a successful fishing trip pulls a sled loaded with salmon. The total mass of the sled and salmon is 50.0 kg, and the Eskimo exerts a force on the sled by pulling on the rope. The coefficient of kinetic friction between the sled and the ground is 0.200. (a) The Eskimo pulls the sled 6.00 m, exerting a force of 1.15 102 N at an angle of θ = 0°. Find the work done on the...

A boy coasts down a hill on a sled, reaching a level surface at the bottom with a speed of 7.0 m/s. if the coefficient of friction between the sled's runners and the snow is 0.050 and the boy and sled together weigh 600 N, how far does the sled travel on the level surface before coming to rest? A woman at an airport is towing her 20.0-kg suitcase at constant speed...

You are pulling a 6.8 kg box with rope with a force of 5.5 N. The rope is 35° above thehorizontal. For a while you are pulling across ice that is very smooth. Later you reach a patch of snow which has a kinetic coefficient of friction of 0.2 and a static coefficient of friction of 0.35 with the box. A)Draw the free body diagrams for the box when it is on the ice and when it is on the...
