(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

22. The average person passes out an

acceleration of 7g (that is, seven times the

gravitational acceleration on Earth).

Suppose a car is designed to accelerate at

this rate. How much time would be

required for the car to accelerate from rest

to 60.0 miles per hour? (The car would need

rocket boosters!)

2. Relevant equations

3. The attempt at a solution

v1 = 60

v0 = 0

a = 7 * 9.8 => 68.6m/s^2

a = change in velocity/change in time

So, 68.6m/s^2 = 60mph/t

68.6 * t = 60mpg

t = 60/68.6

= 0.87 seconds

I am not sure if this is correct or not.

The answer seems within reason since a very high powered sports car accelerates from 0-60 miles per hour in around 3 seconds, so 0.87 seconds would line up well with the exaggeration of the speed of the car mentioned at the end of the word problem.

Any help is appreciated :).
