How could you use 100 pounds of force to lift a 200 pound weight? Explain precisely, listing any necessary distances and details. (This will take some converting!) DO NOT POST LINKS.

What tightening torque should be used for a hexagonal head screw (not split-bolt) on a 250 kcmil conductor?

Which statement is true? a) the work done to lift an object 6 meters is greater than the gravitational potential energy it gains. b) the work required to push an object is less than the work required to pull an object the same distance. c) the work required to raise an object to a height is equal to the gravitational potential energy the object gains. d) the work done against gravity to lift an object straight up is greater than the work required to roll it up a ramp.

The momentum of a man riding his bicycle downhill can be calculated. the bicycle and the man have a combined mass of 40 kg. the velocity of the bicycle is 10 m/s. calculate the momentum.
