You are standing next to your friend, ready to race across a 100-meter field. When the go signal is given, you take 5 seconds to get to your maximum sprinting speed of 12 miles per hour (that’s about 5.4 meters per second). What is your acceleration, in meters per second squared? After you cross the finish line, you slow down and come to a stop, breathing hard. It takes you 10 seconds to come to a stop. What is your acceleration?
