Calculate the power of a machine performing 75J work in 10 seconds.
May 21, 2021 | education
| 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.
