Problem 45PE

(a) What is the power output in watts and horsepower of a 70.0-kg sprinter who accelerates from rest to 10.0 m/s in 3.00 s? (b) Considering the amount of power generated, do you think a well-trained athlete could do this repetitively for long periods of time?

Step-by-Step Solution:

Step-by-step solution Step 1 of 6 The equation to find the power is, . Here is the power, is the energy used and is the time. Step 2 of 6 (a) The kinetic energy of the sprinter, who accelerates from rest to 10.0 m /s, Here is the mass of the sprinter and is the final velocity of the sprinter. Step 3 of 6 Use the formula to find the power,
