  1. From the top of a 70 m building, you throw a ball straight up at 6 m/s.  The ball misses the building on the way down.
    1. What is the maximum height of the ball?
    2. What is the velocity of the ball after 2 s?
    3. What is the final velocity of the ball (just before it hits the ground)
    4. Now, the ball is thrown straight down at 6 m/s. What is the velocity of the ball after 2 s?
    5. Using the initial velocity from part d, now what is the final velocity of the ball (just before it hits the ground)?
