(1) You are sitting on a skateboard on the top of a hill. The hill has a 20% grade to it. The coefficient of rolling friction for you is μr “ 0.2. You have a mass of m “ 80kg.
(a) What is the work done by gravity as when you roll a distance of 50m down the hill (that is along the hypotenuse of the hill, not elevation)?
(b) What is the work done by rolling friction as when you roll a distance of 50m down the hill (that is along the hypotenuse of the hill, not elevation)?
(c) What is the work done by normal force as when you roll a distance of 50m down the hill (that is along the hypotenuse of the hill, not elevation)?

A pancake-shaped solid wood disk (m = 1.4 kg) is placed at the top of an inclined plane. It begins to roll down the plane on its own. A) Which is larger during this rolling, the work done by friction to increase the rotational speed or the work done by friction to keep the object from linearly moving down the plane? B) What is the linear acceleration of the disk referred to if the angle of the hill is 30°?...

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...

a 1750kg car is parked at the top of a hill with an incline of 12 degrees. Its brakes fail and the car starts rolling down the hill. a) how long will it take for the car to travel 200m and reach the bottom of the hill? (the coefficient of rolling friction between the tires and the road is 0.10) b) what will be its velocity at the bottom?

1) A solid ball of mass M and radius R rolls without slipping down a hill with slope tan θ. (That is θ is the angle of the hill relative to the horizontal direction.) What is the static frictional force acting on it? It is possible to solve this question in a fairly simple way using two ingredients: a) As derived in the worksheet when an object of moment of inertia I, mass M and radius R starts at rest...
