As you are driving to school one day, you pass a construction site of a new building and you stop to watch for a few minutes. A crane is lifting a batch of bricks on a pallet to an upper floor of the building. Suddenly a brick falls off the rising pallet. You measure the time it takes for the brick to hit the ground and you find it to be 2.5 seconds. The crane has height markings. You saw the brick fell off the pallet at a height of 30.7 meters above the ground. A falling brick can be dangerous, and you wonder how fast the brick was moving when it hit the ground. Since you are taking physics, you quickly calculate the answer.
