Final answer:
The power needed to move an object 8.5 m with a force of 1,497 N in 15 seconds is 848.3 W, which does not match any of the options provided, suggesting a possible error in the question.
Step-by-step explanation:
To calculate the power required to move an object 8.5 m with a force of 1,497 N in 15 seconds, we use the definition of power as the rate of doing work, where work is the product of force and displacement.
The equation for power (P) can be expressed as:
P = Work done / Time
Work done (W) is the product of the force (F) applied and the displacement (s) moved by the force, so W = F × s. Substituting the given values:
W = 1,497 N × 8.5 m = 12,724.5 J
We then divide the work done by the time (t) to find the power:
P = 12,724.5 J / 15 s = 848.3 W
Therefore, the power required is 848.3 watts (W), which is not an option in the given choices. This indicates there might have been a typographical error in the test question or options.
