Two workers are loading crates onto a pick up truck. Worker 1 lifts his crate straight up from the ground to the truck. Worker 2 slides his crate up a ramp which has frictionless rollers. Which statement is true about the work being done on the crate?



a. Worker 1 does more work than worker 2.

b. Worker 2 does more work than worker 1.

c. Both workers do the same amount of work.

d. Can not be determined because the angle of the ramp is unknown.

e. The mass is unknown therefore none of the statements are true.

    Matt. We are not going to do your thinking for you. We will be happy to guide or critique your thinking. We wouldn't want anyone to get the idea you are answer mooching.
