First, I am not a student. I'm looking to do some modifications to a car and I'm not sure what to do.

1. The problem statement, all variables and given/known data

a 2.0 L, 4 cylinder engine w/ 146 hp

curb weight = 1418 kg

0-60 mph time of 8.6 s

0.25 mile time of 16.7 s at a top speed of 81.8 mph

What distance (miles) would be covered going from 0-47 mph?


2. Relevant equations

1 hour = 3600 s
60 mph = 0.0167 miles/s
47 mph = 0.013056 miles/s

3. The attempt at a solution

where do I go from here?

Assuming constant acceleration you will want to use the 1D kinematic equations.

It might be handy to convert speed to metres per second.

A car however, does not undergo constant acceleration.
