11. If an object in free fall takes 3.8 seconds to hit the ground, how far did it fall? 12. While sitting in class, your calculator falls off your desk that is 1.2 meters tall. What is the velocity of your calculator as it hits the ground? 13. You throw a penny off a bridge into a river with a horizontal velocity of 23 m/s. The penny lands 35 meters away. How long was the penny in the air and how high was the bridge? 14. A rock rolls off a 40 m cliff with a velocity of 12 m/s. What is the rock's vertical velocity as it hits the ground and how far away did it land from the cliff? tr
