Question

1. A person starting from rest accelerates constantly at 1m/s2 for 5 seconds. What is his final velocity?

2. The same person slows down with constant acceleration from the final velocity in #1 to stop (0 m/s) in 2 seconds. What is his acceleration during this time?
3. How much displacement does the person experience during the motion described in #1?
4. How much displacement does the person experience during the motion described in #2?
5. What is the person's average velocity during the entire trip? (hint: Average velocity = total displacement / total time)
