A solid cylinder of radius R and mass m, and moment of inertia mR2/2, starts from rest and rolls down a hill without slipping.
A solid cylinder of radius R and mass m, and moment of inertia mR2/2, starts from rest and rolls down a hill without slipping. At the bottom of the hill, the speed of the center of mass is 4.7 m/sec. A hollow cylinder (moment of inertia mR2) with the same mass and same radius also rolls down the same hill starting from rest. What is the speed of the center of mass of the hollow cylinder at the bottom of the hill, in m/sec?

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...
A 200 kg concrete culvert (a hollow cylinder with radius 0.50 m) rolls from rest without slipping 50 m down a road with inclination 10°
A 200 kg concrete culvert (a hollow cylinder with radius 0.50 m) rolls from rest without slipping 50 m down a road with inclination 10°. What is the culvert's linear speed at the bottom? (The moment of inertia is I=MR2). Assume that gravity is the only force that is acting in initiating the motion of the culvert (creates torque).

A hollow cylinder is released from rest and rolls down the incline without slipping. The incline has an angle of thera=40 degrees with the horizontal. The mass and radius of the cylinder is M=5kg and R=0.55m respectively. Moment of inertia of a hollow cylinder is I=MR^2. a)Draw the free body diagram of the hollow cylinder showing all the forces and their components. b) Using newtons 2nd law for linear and rotational motion, derive an expression for linear acceleration of the...
A solid cylinder of radius 10 cm and mass 13 kg starts from rest and rolls without slipping a distance of 6.0 m down a house roof that is inclined at 30°
A solid cylinder of radius 10 cm and mass 13 kg starts from rest and rolls without slipping a distance of 6.0 m down a house roof that is inclined at 30°. (See the figure.) What is the angular speed of the cylinder about its center as it leaves the house roof? The outside wall of the house is 5 m high. How far from the edge of the roof does the cylinder hit the level ground?
