Question

a jet ski exerts a constant forward force of 800 n while moving at a constant speed of 15 m/s. what is the jet skis power output? 12,000 w 1,200 w 53 w 120 w

Explanation:

Step1: Recall the formula for power

Power \( P = F\times v\), where \(F\) is the force and \(v\) is the velocity.

Step2: Substitute the given values

Given \(F = 800\space N\) and \(v=15\space m/s\). Then \(P=800\times15\).

Step3: Calculate the power

\(P = 800\times15=12000\space W\)

Answer:

12,000 W
