Suppose you are driving a car at 80 miles per hour. Again decelerating at 16 feet per second squared it will take you seconds to stop. During that time you will travel feet. Assuming that it takes you 1 second to react to an emergency before you start braking, at the same initial speed, and the same constant deceleration, you will travel a total of feet, before coming to a stop.

The other day, while riding my bike, I was forced to stop quickly to avoid a squirrel in the middle of the road 60 feet ahead. I decelerated at a constant rate of 15 ft/sec², skidding all the way. One second into the slide, my trip computer said I was going 27 ft/sec. How far did I skid before stopping? Did I avoid hitting the squirrel? Round to the nearest tenth
