Best ResponseYou've already chosen the best response.0values for mass: 100, 150, 200, 250 values for distance: 2.25, 1.76, 1.50, 1.25 values for time: 0.151, 0.052, 0.217, 0.206 in case it was too messy above lol :P

Best ResponseYou've already chosen the best response.1here we have to compute this quantity: \[\frac{{mgD}}{t}\] for all of your four cases

Best ResponseYou've already chosen the best response.1since the power developed by the worker is given by this formula: \[\frac{{mgD}}{t}\]

Best ResponseYou've already chosen the best response.1for example, if we consider the case of worker A, we get: \[\frac{{mgD}}{t} \cong 14618\;Watt\]

Best ResponseYou've already chosen the best response.1\[\frac{{mgD}}{t} = \frac{{100 \times 2.25 \times 9.81}}{{0.151}} \cong 14618\;Watt\]

Best ResponseYou've already chosen the best response.0oh okay! so for B we get 49804 C=13562 D=14881 so our solution is weighlifter D?
