28. The mass of a steel building frame is 5500 kg. What power is used to raise it to a helght of 5.0 m If the work is done in 12.0 seconds?
Remember to include your data, equation, and work when solving this problem.

Respuesta :

Answer:

2292W

Explanation:

Use the formula for energy first:

[tex]E=D*M[/tex]

Where E = Energy || D = Distance || M = Mass.

Solve that equation:

E = 5 * 5500    ==>     27500J

To find power, divide energy per time:

27500J / 12s =~  2292W
