## anonymous one year ago If a runner does 1,500 J of work over 10.0 s, then how much power does she have? 150 W , 1000 W , 1500 W , or 15000 W ? :/

1. Michele_Laino

it is simple, since the power P, is given by the subsequent formula: $P = \frac{L}{{\Delta t}}$

2. Michele_Laino

namely: $P = \frac{L}{{\Delta t}} = \frac{{1500}}{{10}}$

so 150? that is our solution? 150 W ?

4. Michele_Laino

yes! that's right!

5. anonymous
