A young 49-kg ice hockey goalie, originally at rest, deflects a 0.16-kg hockey puck slapped at him at a speed of 35.5 m/s. In this problem, take the original direction of the puck as positive. Suppose the goalie and the ice puck have an elastic collision and the puck is reflected back on the direction from which it came. What would the final velocity of the pack in meters per second, be in the case

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.
