Answer:
P=W/t
Step-by-step explanation:
Work is given by the equation W=FxD
- F is force
- D is distance
"the rate of doing work is power" is saying that the rate in time (s) for work is given by Power.
Meaning that Power = Work/time
Think of it like this, a) find the work for a force of 150N over a distance of 10m.
W = (150N)(10m)
W = 1500J
Lets say in the question it also tells you that this work is done for 10 seconds. b)
Given by the equation P=W/t
You would simply plug in these values
P = (1500J)/(10s)
P = 150 W
The units for power is Watts.
In conclusion, the Power is the rate of work done. Also could be thought of as Work per second.
