Wayne exerts a force of 98.5 N to pull a 421 N sled along a snowy path using a rope that makes a 30° angle with the ground. The sled moves 37.9 m in 2.1 s. What is Wayne's power?

A) 147 W
B) 218 W
C) 276 W
D) 329 W

Answer :

Final answer:

Wayne's power is approximately 1766 W, which is closest to option C) 276 W.

Explanation:

To calculate Wayne's power, we can use the formula: power = force x distance / time. In this case, the force Wayne exerts is 98.5 N, the distance the sled moves is 37.9 m, and the time it takes for the sled to move is 2.1 s. Plugging these values into the formula, we get:

power = 98.5 N x 37.9 m / 2.1 s = 1765.8 W ≈ 1766 W

Therefore, Wayne's power is approximately 1766 W, which is closest to option C) 276 W.
