Homework Statement A Carnot engine moves a piston which applies 5N of force to a rotating disc by moving a piston 0.25cm for a total of 5W of power. If the high temperature reservoir is 100K, what must the temperature of the low temperature reservoir be? Homework Equations The efficiency of a...

Confused on where to go from here

I also know Icom of a disk is 1/2Mr^2

I know alpha=T/I So I am guessing the force moving the box is the torque in the wheel of the bike.

1. A cyclist is attached to a rope which is looped over a pulley (disc of mass 10kg and radius 0.5m). The rope is then attached to a hanging block of mass 5kg. What force must the cyclist generate such that the block will move with an acceleration of 2.25 m/s2. Let’s make the assumption that...
