. A driver notices an upcoming speed limit change from 45 mi/h (20 m/s) to 25 mi/h (11 m/s). If she estimates the speed limit will change in 50 m. a) Sketch the scenario listing given information. b) Use the time independent kinematic equation v(final)^2 = v(initial)^2 + 2 a s to determine the acceleration needed to reach the new speed limit before it begins? c) Is your result for acceleration a positive or negative value and does it represent speeding up or slowing down? * 15 points
