P2.4-4) A car initially traveling at 60 mph coasts for 5 seconds. Due to friction and wind resistance, the car decelerates while coasting at a rate of 1 ft/s2. After the 5 seconds of coasting, the driver applies the brakes and decelerates at a constant rate eventually bringing the car to a stop. If the total time that the car travels is 8 seconds, determine the car's braking acceleration. Given: Find: Solution: Draw the acceleration and velocity curves. v (ft/s)...
