Power generated by a 100m sprinter.
hai all,
i've been thinking about how much horsepower does a human generate during a 100m sprint...
(after my friends joking with me by telling me running on dyno machine's roller to measure my horsepower. )
is it possible for me to use P = (F*d)/t, where
F is the sprinter weight, (coz i think its the only force/mass that been moved, or got any other force involve, too?)
d is 100m and
t is his sprint time.
let's say mass of the sprinter is 60kg,
therefore his weight is 60kg*9.81m/s^2 = 588.6N
and his 100m sprint time is 10s sharp.
so, power generated by the sprinter is,
P = (588.6*100)/10
P = 5,886W
P = 5,886W*(1hp/746W)
P = 7.89hp
its so true that if the sprinter can sprint 100m less than 10s, his horsepower generated for the sprint will be higher, which is make sense to me.
am i correct?
thanx all.
