Answer:
Power, P = 600 watts
Explanation:
It is given that,
Mass of sprinter, m = 54 kg
Speed, v = 10 m/s
Time taken, t = 3 s
We need to find the average power generated. The work done divided by time taken is called power generated by the sprinter i.e.
[tex]P=\dfrac{W}{t}[/tex]
Work done is equal to the change in kinetic energy of the sprinter.
[tex]P=\dfrac{\dfrac{1}{2}mv^2}{t}[/tex]
[tex]P=\dfrac{\dfrac{1}{2}\times 54\ kg\times (10\ m/s)^2}{3\ s}[/tex]
P = 900 watts
So, the average power generated by the sprinter is 900 watts. Hence, this is the required solution.
