Explanation:
It is given that,
Speed, v₁ = 7.7 m/s
We need to find the velocity after it has risen 1 meter above the lowest point. Let it is given by v₂. Using the conservation of energy as :




So, the velocity after it has risen 1 meter above the lowest point is 6.26 m/s. Hence, this is the required solution.
Force = mass * acceleration = 1500kg * 8m/s²
You should slow your pwc to "slow, no wake speed" when within 100 feet of anchored vessels or non-motorized craft.
<h3>What is Slow-no-wake?</h3>
This is the process of operating a personal watercraft at the slowest possible speed.
This helps to maintain steerage which prevents different forms of accident or risks when in motion in the water.
