Two cars start from rest at the same location

and at the same instant and race along a straight

track. Car A accelerates at 6.6 fps2 to a speed of

90 mph and then runs at this constant speed. Car B

accelerates at 4.4 fps2 to a speed of 96 mph and

then runs a a constant speed.

(a) Which car will with a 3-mile race and by what

distance?

(b) What will be the maximum lead of A over B?

(c) How far will the cars have traveled when B

passes A?
