A12-pack of omni-cola (mass 4.30 kg) is initially at rest ona horizontal floor. it is then pushed in a straight line for1.20 m by a trained dog who exerts ahorizontal force with magnitude 39.0n.
(a) use the work-energy theorem to find the final speedof the 12-pack if there is no friction between the 12-pack and thefloor.
m/s
(b) use the work-energy theorem to find the final speed of the12-pack if the coefficient of kinetic friction between the 12-packand the floor is 0.30.

Engines for propeller-driven aircraft are limited in their maximum rotational speed by the fact that the tip speed of the propeller must not approach the speed of sound in air (mach i). taking 6 ft as a typical diameter for a propeller of a light airplane and 1100 fils as the speed of sound, find the upper limit on the rpm (revolutions per minute) of the propeller shaft.
