... The rigid body shown rotates about an axis through its center of mass and perpendicular to the paper. If M = 2.0 kg and L = 80 cm, what is the kinetic energy of this object when its angular speed about this axis is equal to 5.0 rad/s? Neglect the mass of the connecting rod and treat the masses as pa ...

... A friction force between two objects in contact opposes the sliding of one object over the surface of the adjacent one. It is tangent to the surface of the adjacent object and opposite in direction to the velocity of the moving object. The magnitude of the frictional force is assumed to be proportio ...

... 12.3 Newton’s Third Law of Motion and Momentum According to Newton’s third law of motion, whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first object. An object has a large momentum if the product of its mass and velocity is large. ...
