If a runner has a power output of 150 W over 10.0 s, then how much work does she do?

1 answer:

5 0

The amount of work done by a certain body is the product of the power given and the time. Mathematically,
Work = Power x time
Substituting the known values,
Work = (150 W) x (10 s)
= 1500 N.m
= 1500 J

Assume it takes 5.00 minutes to fill a 50.0-gal gasoline tank. (1 U.S. gal = 231 in.3).

dolphi86 [110]

   (50 gal / 5 min) x (.0037854 m³/gal) x (1 min / 60 sec)

   = (50 · 0.0037854 · 1) / (5 · 60) m³/sec

   = 0.000631 m³/sec
