The time, t in seconds that it takes a car to travel a quarter-mile when starting from a full stop can be estimated by using the
formula:
(see image)
Where w = weight of the car
p = power delivered by the engine in horsepower (hp)
If the quarter-mile time for a 3,590-pound car is 13.4 s, how much power does its engine deliver? Round to the nearest pound.
Assignment:
Natasha and Daniel worked out this problem. Natasha’s answer was 295 hp and Daniel’s was 679 hp.
1. Who was right?
2. How did you determine who was right? Show each step of how each of them solved the problem.
3. Set up your Fantasy Race. Research two different cars/trucks. What is the average hp and weight of each? Based on the formula, how fast can each reach a quarter-mile? Show all the work for each.
