2. A worker applies 170 N of force on a lever to lift a 1250 N crate 0.10 m. a) If the lever is 100% efficient, how far does he need to push his side?

Your response should include all of your work.

0.735m

Explanation:

Efficiency = Work output/Work input * 100

100 = 1250*0.1/170de * 100

100/100 = 125/170de

de is the distance moved by effort

1 = 125/170d

170d = 125

d = 125/170

d = 0.735m

Hence he needs to push by 0.735m
