A golf ball rolls uphill toward a mini-golf hole. Assume that the direction toward the hole is positive. If the ball starts with a speed of 2.0 m/s and slows at a rate of 0.50 m/s^2, what is its velocity after 2.0 seconds?

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.
