During the next twelve seconds, the car slows down and its average acceleration is a1. Over the next six seconds, the car slows down even further, and its average acceleration is a2. The speed of the car is 28.0 m / s. The ratio of the average acceleration values is a1 / a2 = 1.50. (a) Find the speed of the car at the end of the initial twelve second interval. (b) Calculate the total distance traveled by the car before stopping.arrow_forwardA swimmer bounces straight up from a diving board and falls feet first into a pool.
