Answer:</h3>
6.38 seconds
<h3>
Explanation:</h3>
We are given;
- The force exerted by the runner as 234 N
- Power used = 1100 W
- Distance as 30.0 m
We are required to determine the time taken to run the distance;
- We know that power is the rate of work done
That is;
Power = work done ÷ time
But, work done = Force × distance
Therefore;
Work done = 234 N × 30 m
= 7020 Joules
Therefore, from the formula, Power = work done ÷ time
Time = Work done ÷ power
Thus;
Time = 7020 J ÷ 1100 W
= 6.38 seconds
Hence, the time taken is 6.38 seconds
The statement “the separation (distance) between
the rocks will stay the same as they fall” is TRUE. The correct answer
