If a force of 50 N moves an object a distance of 5 m in 10 s, what is the power output?
a. 250 W
b. 50 W
c. 10 W
d. 5 W
The formula for power is P = W/t, where W is work done and t is time. Work done is force multiplied by distance, so W = F*d. In this case, F = 50 N, d = 5 m, and t = 10 s.
W = 50 N * 5 m = 250 J
P = 250 J / 10 s = 25 W
Therefore, the power output is 25 W, which is not one of the given options. It seems like the closest option would be a. 250 W, but the calculation shows that the power output is actually 25 W.
