1) A man driving a car at 45 mph suddenly sees an object in the road 60 ft ahead. What constant deceleration is required to stop the car in this distance? 2) A train with a top speed of 50 mph cannot accelerate or decelerate faster than 4 ft/s². What is the minimum distance between two trains stops in order for the train to be able to reach its speed? 3) If a car travelling at 60 mph suddenly locks its brakes and skids 200 ft, how long will it take for the car to come to a complete stop? 1) A man driving a car at 45 mph suddenly sees an object in the road 60 ft ahead.
