Answer:

Step-by-step explanation:
Power is the work done divided by the time. It can be found using the following formula.

The force is 50 Newtons, the distance is 10 meters, and the time is 20 seconds.

Substitute the values into the formula.

Multiply the numerator first.

- 1 Newton meter is equal to 1 Joule.
- Therefore, the numerator is equal to 500 Joules.

Divide.

- 1 Joule per second is equal to 1 Watt.
- Our answer is equal to 25 W

It takes 25 Watts to lift a 50 Newton object 10 meters high in 20 seconds.
