<span>The student's power rating is approximately 800W.
</span>
Power is the rate of doing work. Its SI unit is Watt. 1 W = 1J/sec

Given: <span>The work done to get to the top is 1200 Joules
</span>
Time = 1.5 seconds.

Power = \frac{work done}{time} &#10;=  \frac{1200J}{1.5 sec} &#10;= 800J/sec &#10;= 800W

Can someone explain the normal force? where does it come from? ...?
Vilka [71]
<span>The normal force is the support force exerted upon an object which is in contact with another stable object. For example, if a book is resting upon a surface, then the surface is exerting an upward force upon the book in order to support the weight of the book. The normal force in itseñf comes from the third law of Newton as a reactive force</span>
