Problem 37PE

500-kg dragster accelerates from rest to a final speed of 110 m/s in 400 m (about a quarter of a mile) and encounters an average frictional force of 1200 N. What is its average power output in watts and horsepower if this takes 7.30 s?

Step-by-Step Solution:

Step-by-step solution Step 1 of 5 The equation to find the power is, Here is the power, is the work done and is the time period. Step 2 of 5 The dragster accelerates from rest, therefore the total work done is equal the gain in kinetic energy, Here is the total work, is the frictional force, is the displacement, is the mass and is the velocity. Step 3 of 5 Calculate the average power output,
