a box pushed across the floor for a dis tance of 5 meters with a force of 50 newtons in 5 second

how much work is done?
what is the power?

To calculate the work done, you can use the formula:

Work = Force × Distance

In this case, the force applied is 50 newtons, and the distance covered is 5 meters. So, the work done would be:

Work = 50 N × 5 m = 250 Joules

Therefore, the work done in pushing the box across the floor is 250 Joules.

To calculate the power, you can use the formula:

Power = Work ÷ Time

Here, we already determined the work done as 250 Joules. The time taken to complete the work is given as 5 seconds. So, the power would be:

Power = 250 J ÷ 5 s = 50 Watts

Hence, the power exerted in pushing the box across the floor is 50 Watts.
