Work - Conceptual Example 7.1-5

 

You would like to lift a block of mass m from the floor to a height d at a constant rate by applying a constant force. You have the opportunity to use a simple machine (a frictionless ramp) (Case (a)), or you can simply lift the block straight up (Case (b)).

 

 

In which case do you do less work?
