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

A motorist enters a freeway at 45km/h and accelerates uniformly to 99 km/h. From the odometer of the car, the driver knows she has travelled 0.2km. Find the acceleration of the car.

2. Relevant equations

3. The attempt at a solution

I attempted this:

v^{2}= u^{2}+ 2as

Substituting the values in I got this:

(99^{2}-45^{2})/0.4 = a

this gives 19440, so converting to m/sec I think I get 5400 m/sec^{2}

This is definitely not right, any ideas why?

Cheers,

Adrian :)
