Who has the most power? athlete a (bench presses 100 kg over 0.6 m in 0.5 s) athlete b (bench presses 150 kg over 0.6 m in 1.0 s) athlete c (bench presses 200 kg over 0.6 m in 2.0 s) athlete d (bench presses 250 kg over 0.6 m in 2.5 s)

Athlete A

Explanation:

Power is the rate of doing work and it is calculated as follows:

Power = work done/time taken = mgh/t

(for work being done against gravity)

So for athlete A

P = (100 kg * 9.8 N/kg* 0.6m)/0.5 s = 1176 W

For athlete B

P = (150 kg * 9.8 N/kg* 0.6m)/1 s = 882 W

For athlete C

P = (200 kg * 9.8 N/kg* 0.6m)/2 s = 588 W

For athlete D

P = (250 kg * 9.8 N/kg* 0.6m)/2.5 s = 588
