Question

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

? :/

Answer 1

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

Answer 2

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

Answer 3

so 150? that is our solution? 150 W ?

Answer 4

yes! that's right!

Answer 5

yay!! :) thanks!

Answer 6
