Car A and Car B are initially traveling at 55 ft/sec. Car B applies the brakes and slows down at a rate of 9.5 ft/sec^2. Car A applies the brakes 0.24 seconds later which slows the car down at a rate of A ft/sec^2? Find the minimum acceleration of car A to stop before hitting car B if the starting distance is 9.0.

Question

Need only a handwritten solution only (not a typed one).

Car A and Car B are initially traveling at 55 ft/sec. Car B applies
the brakes and slows down at a rate of 9.5 ft/sec^2. Car A
applies the brakes 0.24 seconds later which slows the car down
at a rate of A ft/sec^2? Find the minimum acceleration of car A to
stop before hitting car B if the starting distance is 9.0.
Given:
Starting velocity of both cars = 55 ft/sec
Starting distance between cars = 9.0
Car A starts slowing down 0.24 seconds after B does
Car B slows down at 9.5 ft/sec^2
Include graph showing position of each car as a function of time
