A cylinder of mass 10.0 kg rolls without slipping on a horizontal surface. At a certain instant, its center of mass has a speed of 10.0 m/s. Determine (a) the translational kinetic energy of its center of mass, (b) the rotational kinetic energy about its center of mass, and (c) its total energy

Nonconservative Forces Work Done By Nonconservative Forces ● In the presence of non-conservative forces, the total mechanical energy is not conserved: ○ W totalW conservativnonconservative ○ W = − ΔU + W = ΔK total nc ○ W nc ΔK + ΔU = ΔE Examples ● What height H must we release the car if it just makes it around the circular loop of radius R ● A shot put (m = 7.26 kg) is shot at an angle of 43.4 degrees and released from a height of 1.82 m above ground level then it lands with a final velocity of 20m/s. It lands a horizontal distance of 17.7 m from the release point. With what speed does the shot put leave the thrower’s hand ● A block of mass
