George works for a moving company. he is paid $1 for every 1,000 newton-meters of work. on thursday, george used 600 newtons of force moving a piano 80 meters. it took him 50 minutes to move the piano. how much should george get paid? how fast did he move the piano on average?

Hi!

Explanation:

For every 1000Nm of work, George gets paid $1. So if he moves a piano 80 meters through a force of 600N, he is doing a work of 48000Nm through the formula of work ( force (600)  x distance (80m) )

So if he gets paid $1 for 1000 Nm of work, he gets paid 48000/1000 for this work, which amounts to $48.

Explanation:

To calculate the average speed at which he moved the piano, we can apply the formula of Speed ( total distance/total time taken to cover the distance).

We can convert the time from minutes into seconds by multiplying it by the value of 60. So,

50 minutes = 50 x 60 = 3000 seconds

Using the formula of average speed,

Average speed = 80m / 3000s = 0.0266666 = ~0.027m/s

Hope this helps!
