Based on the given details with this question, I can say that the direction of motion is not conserved. This is because the boat is subjected to an external force because of water resistance. So, the answer for this question would be NO.
The plane has a centripetal acceleration <em>a</em> of
<em>a</em> = <em>v</em> ²/<em>r</em>
where <em>v</em> is the plane's tangential speed and <em>r</em> is the radius of the circle. By Newton's second law,
<em>F</em> = <em>mv</em> ²/<em>r</em>
Solve for the mass <em>m</em> :
<em>m</em> = <em>Fr</em>/<em>v</em> ² = (3000 N) (18.3 m) / (55.0 m/s)² ≈ 18.1 kg
It is currently organised by the increasing atomic # based on the actual nuclear charge of the elements
