Final answer:
The person uses 100 Watts of power to move the piano 10 meters in 10 seconds, calculated using the power formula which takes into account the work done and the time taken.
Step-by-step explanation:
To calculate the power used to move a piano, we need to use the formula for power in terms of work done over time. Power is defined as work done per unit time, and work is defined as force times distance. In this case, the force used to move the piano is 100 N and the distance moved is 10 meters.
The formula to find work is:
- Work (W) = Force (F) x Distance (d)
Substituting the values:
- W = 100 N x 10 m = 1000 J (Joules)
Now, using the time of 10 seconds, we can find power using the formula:
- Power (P) = Work (W) / Time (t)
Substituting the values:
- P = 1000 J / 10 s = 100 Watts
Therefore, the person would use 100 Watts of power to move the piano 10 meters in 10 seconds.
