a)Find the power of the runner is exerting while running.
b)Find the total energy exerted by the runner in a 10k run
1a) power = energy / time
= 300000J/ 3600s
=83.3333 j/s
b) 5m/h = 0.0013889 m/s
speed = dist /time
0.0013889 = 10000 / t
t = 719994.24s
83.3333 = energy / 719994.24
energy = 59999496
