Calculate the power of a machine performing 75J work in 10 seconds.

A = 75 Joules – the work done by some machine;

t = 10 seconds – the time interval during which the machine performs work A.

It is required to determine N (Watt) – the power of the machine.

To determine the power of the machine, you must use the following formula:

A = N * t, from here we find:

N = A / t = 75/10 = 7.5 watts.

Answer: the power of the machine is 7.5 watts.
