# Kim's Power Calculation: How much power does Kim use?

## Calculation of Kim's Power:

**Power = Work Done / Time**

Power is the amount of energy transferred or converted per unit time. Work done on an object is defined as the magnitude of the force multiplied by the distance moved by the object in the direction of the applied force. Therefore, the formula for power can be derived as:

**Power = (Force * Distance) / Time**

By substituting the given values (Force = 800N, Distance = 5.0m, Time = 20s) into the formula, we can calculate Kim's power:

**Power = (800N * 5.0m) / 20s = 200 Watts**

Therefore, Kim uses 200W of power when pushing the block horizontally with a force of 800N across a distance of 5.0m in 20s.
