Question
Hollie carries a heavy tin of paint up a ladder. It takes her 12 seconds and she generates a power of 2.1 kW. Calculate how much work Hollie did.
Solution
To calculate the work done, we can use the formula for power which is Power = Work/Time.
Given: Power (P) = 2.1 kW = 2100 W (since 1 kW = 1000 W) Time (t) = 12 seconds
We can rearrange the formula to solve for Work (W):
W = P * t
Substituting the given values:
W = 2100 W * 12 s = 25200 Joules
So, Hollie did 25200 Joules of work.
