...>P = (mgh)/t = (42.3 x 10 x 0.19 x 9 x 10)/33.3 = 217W (3 s.f.)
Person B
P = (mgh)/t = (87.7 x 10 x 0.19 x 9 x 10)/25.3 = 593W (3 s.f.)
The respective values for the powers of each person show that Person B is 376W more powerful than Person A and so I decided to look at each of the dependent variables to find the reason why.
