Question

Four weightlifters a through d enter a competition. The mass and distance that each lifts are shown in the table. Which weightlifter does the most work?.

Answer 1

The weightlifter that did the most work is; Weightlifter D

How to Calculate the Workdone

The masses of the weightlifters and their distances are;

Weighlifter   Mass(kg) Distance(m)

      A             100.0        2.25

      B             150.0        1.76

      C             200          1.50

      D             275           1.25

Formula for work done is;

W = mgh

Thus;

Work done by weightlifter A = 100 * 9.8 * 2.25 = 2205 J

Work done by weightlifter B = 150 * 9.8 * 1.76 = 2,587.2 J

Work done by weightlifter C = 200 * 9.8 * 1.5 = 2940 J

Word done by weightlifter D = 275 * 9.8 * 1.25 = 3,368.75 J
