the citizen of return to San Juan, leaves Arecibo at 3:00 p.m. Travels at 36.0 m / s when
he turns off the engine of his car at the height of Barceloneta. For the next twelve seconds, the
car slows down and its average acceleration is a1. For the next six
seconds, the car slows down even more, and its average acceleration is a2. Speed
of the car is 28.0 m / s. The ratio of the average acceleration values ​​is a1 / a2 = 1.50.
(a) Find the VELOCITY of the car at the end of the initial twelve second interval.
(b) Calculate the total distance traveled by the car before stops.
