16. Assume that you drop a rock from the top of a tall cliff and it takes 3 seconds for the rock to fall to the bottom of the cliff. What is the rock’s velocity when it reaches the bottom? How do you know?
17. When you shoot an arrow at a target, why should you aim above the bull’s eye if you want the arrow to hit the bull’s eye?
17, due to the gravitational forces and wind drag placed upon the arrow while it is in motion it will decrease the speed over a certain distance. Thus, resulting in the arrow to drop a little lower in height, hitting the bullseye.
