2. An astronaut drops a rock off the rim of a 155 m high cliff on the moon, where the free-fall
acceleration is −1.6 m/s2. Find the velocity of the rock when it hits the ground.
3. While standing on a 6.0 m tall building, Christine kicks a soccer ball straight up with an initial
velocity of +9.5 m/s. How high does the soccer ball go?
4. While standing on the edge of a 6.0 m tall building, Bobby kicks a soccer ball straight up with an
