When two cars A and B are next to one another they are traveling in the same direction with speeds V(a) and V(b) respectively. If B maintains its constant speed, while A begins to accelerate at a(A), determine the distance d between the two cars the instant A stops.
I got (v^2 - v(a)^2)/2a(A). The book says that's wrong, but I can't figure out how they got their answer.
What's the book's answer? Also, what level math is this? It looks like it could be Physics or some grade of Calculus.
A question, is V(A) implied to be the same as V(B) when they are next to each other? Is there a "T" of any sort in their answer?
