Aforce of 13 n is applied to the handle of a screwdriver being used to pry off the lid of a
paint can. as the input force moves through a distance of 0.25 m, the screwdriver does 2
j of work on the lid. what is the efficiency of the screwdriver? show your work.

Efficiency = 61.54%

Efficiency is given by the Formula;

Efficiency = work output/work input × 100%

Work input = Input force × distance moved by the input force

                  = 13 N × 0,25

                  =  3.25 Joules

Work output or work done by the screwdriver is 2 Joules

Therefore;

Efficiency = 2/3.25 ×100%

                =  61.54%
