Question

A small car of mass m and a large car of mass 4m drive along a highway at constant speed. They approach a curve of radius r. Both cars maintain the same acceleration a as they travel around the curve. How does the speed of the small car vs compare to the speed of the large car vl as they round the curve?

Answer 1

Answer:

Explanation:

F = mv^2 / r

F*r = mv^2

So F*r is a constant in this problem, which means:

4mvL^2 = mvs^2

4Ll^2 = vs^2
