A motorcycle is following a car that is traveling at constant speedon a straight highway. Initially, the car and the motorcycle areboth traveling at the same speed of 47.0 {mph}, and the distancebetween them is 53.0 {m}. After t1 = 4.00 {s}, the motorcyclestarts to accelerate at a rate of 7.00 {m/s^2}. The motorcyclecatches up with the car at some time t2.
(A) How long does it take from the moment when the motorcyclestarts to accelerate until it catches up with the car? In otherwords, find t2-t1.
(B) How far does the motorcycle travel from the moment it starts toaccelerate (at time t1) until it catches up with the car (at timet2)?
