A physics student is taking a car for a joy ride on a long, empty and perfectly(adsbygoogle = window.adsbygoogle || []).push({});

straight Saskatchewan highway. At the beginning of the joy ride the student has the

car accelerate from rest to some top speed with a (constant) acceleration of 4:50 m=s2

and then maintains that top speed to the end of the ride. The total time taken from

the start of the joy ride to its end is 1:36 minutes and the total distance covered is

3:84 km.

(a) What was the time elapsed during the acceleration phase of the car's motion?

(b) What distance did the car cover during the acceleration phase of its motion?

(c) What was the top speed reached by the car?

Please help. tell me which dervived formula you used!
