A sled weighing 60.0 N is pulled up a snowy hill inclined at 10 degrees to the horizontal at a constant speed so that the coefficient of kinetic friction between sled and snow is 0.070. A penguin weighing 70.0 N rides on the sled. If the coefficient of static friction between penguin and sled is 0.950, find a). the force of friction between the sled and the snow, b). the force of static friction between the penguin and the sled,...

A refrigerator is being pushed up a slight inclined plane of 10 degrees, as is shown in the figure below. The weight of the refrigerator is 550 N. The coefficient of static friction for the base of the refrigerator on the inclined plane is 0.3. The coefficient of kinetic friction for the base of the refrigerator on the inclined plane is 0.1. The refrigerator is 2m high and 1m wide. What is the max height above the inclined plane that...

A bicyclist maintains a constant speed of 4.00 m/s up a hill that is inclined at 10.0 degrees with the horizontal. Calculate the work done by the person and the work done by gravity if the bicycle moves a distance of 19.0 m up the hill. The combined mass of the rider and the bike is 88.0 kg. 1) Calculate the work done by gravity. 2) Calculate the work done by the person.

Our favorite crate full of
armored armadillos is sitting at the bottom of a hill that is
inclined 41° above the horizontal. The crate is 75 kg and the
coefficient of kinetic friction between the crate and the ground is
0.31. Samer decides to drag the crate to the top of the hill, which
is 20 m above the base of the hill. Samer attaches a thin rope to
the crate so that when he pulls, the rope will be...
