Answer:
Sorry to tell you this but there’s no answer for that
Explanation:
Answer:
Total energy =kinetic energy +potential energy.
Moving an object up an inclined plane<span> requires </span>less<span>force </span>than<span> lifting it straight up, at a cost of an increase in the distance moved. The </span>mechanical advantage<span>of an </span>inclined plane<span>, the factor by which the force is reduced, is equal to the ratio of the length of the sloped surface to the height it spans.</span>
Answer:
840 W
Explanation:
The energy expended in hoisting the diver up is given by

<em>m</em> is the mass of the diver, <em>g </em>is the acceleration due to gravity and <em>h</em> is the height.
Using the values in the question and taking <em>g</em> as 9.8 m/s²,

The power is given by

<em>t</em> is the time.
Hence,
