Question

If a runner has a power output of 150 W over 10.0 s, then how much work does she do?15 J1,000 J1,500 J15,000 J

Answer 1

We have the next formula

`P=(W)/(t)`

where P is power, W is work, and t is time

we substitute the values

`150=(W)/(10)`

then we isolate the work

`W=150\cdot10=1500J`

the answer is 1,500 J
