W = E x D | W = 6230 J x 8.95m | W = 55758 J !
In physics, power is the rate at which energy is transferred, used, or transformed. To find how much energy is used per second in Mike Powell world record jump we are going to use the already previously found values to do so.
P = W/t | P = 55758J / 5.5s | P = 10 138 J/S
ET= mgh + (1/2)mv²
= (77kg)(9.8m/s²)(1.35m) + (1/2)(77kg)(12.72m/s)²
= 1019J + 6237J = 7256 J
