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 1 of 5 The equation to find the power is, Here is the power, is the work done and is the time period.
