Given: t = 2 h = 7200 s; n = 10,000; A1 = 40 J Find: N -?
When solving this problem, we use the already known formula:
N = A / t
We know that work A1 = 40 J is performed in 1 step, which means we will find the work performed in 10,000 steps:
A = A1 • n
N = (A1 • n) / t = (40 * 10000) / 7200 ~ 55 W
Answer: N = 55 W
