DRIVING An automobile moving at 12 meters per second on level ground begins to decelerate at a rate of 1.6 meters per second squared. The formula for the distance an object has traveled is d(t) = vt + at^2, where v, is the initial velocity and a is the acceleration. For what value(s) of t does d(t) = 40 meters?​
