A car traveling with velocity v is decelerated by a constant acceleration of magnitude a. It takes a time t to come to rest. If its initial velocity were doubled, the time required to stop would
A) double as well.
B) decrease by a factor of two.
C) stay the same.
D) quadruple.
E) decrease by a factor of four.
