During an epic round of Tug-of-War, Jared and James thought they’d be able to beat Mr. Collins no problem. Together, they applied a force of 350 N pulling to the left. But with one arm on the rope and
the other at his side, Mr. Collins applied a 350 N force to the right. What is the net force and direction
on the rope?

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.
