Answer :
To calculate Elijah's power while performing work, we can use the formula for power:
[tex]\text{Power} = \frac{\text{Work}}{\text{Time}}[/tex]
Here:
- Work is given as 3000 joules.
- Time is given as 15 seconds.
Substitute these values into the formula:
[tex]\text{Power} = \frac{3000 \text{ Joules}}{15 \text{ seconds}}[/tex]
Calculating the above gives:
[tex]\text{Power} = 200 \text{ Watts}[/tex]
Therefore, Elijah's power while pushing the table is 200 Watts.
Explanation:
- Power is a measure of the rate at which work is done or energy is transferred.
- The unit of power is the watt (W), where 1 watt is equal to 1 joule per second.
- By using the power formula, you can find out how much work is done in a certain amount of time, translated into how much energy was used or how much force was applied at a given rate.
Power is given by;
P = E / t
P = 3000 / 15
P= 200W
Simple division
P = E / t
P = 3000 / 15
P= 200W
