The driver of the truck has a speed of 80 ft/sec as it passes position A, and subsequently the truck decreases its speed at a constant rate of 5 ft/sec per second as it travels up the circular hump. The radius of curvature of the road is r = 650 ft and the center of mass G of the driver is h = 6 ft above the road. If 0 = 30°, determine the total acceleration of the driver at positions A and B. (ɑâ = 11.0 ft/sec², aB = 6.74 ft/sec²) A ν B h D 3
