What is the stone's velocity just before hitting the ground? Solution: In the free-fall problems, the important note is choosing the origin. Usually, the throwing releasing or dropping point is the best choice. What is its velocity at the instant of striking at the ground? Solution: Let the origin be the firing point. What is the time interval between dropping the stone and hearing its impact sound? Solution: This motion problem has two parts.
