Average power putting 580 kJ into a car in 8 s

Answer: power = 72,500 W (in horsepower 97.224 hp).

What we know

  • Work / energy: 580 kJ = 580000 J (converted to the unit the formula takes)
  • Time: 8 s

Step by step

Given
W = 580000 J, t = 8 s
Formula
P = W / t
Substitute
P = 580000 / 8
Result
P = 72,500 W

All results

The physics

Power is how fast energy flows: joules per second, measured in watts. Same work done in half the time means double the power.
