In the video, I drop a ball off a three-story balcony. We know that objects in freefall follow the equation for height h, in meters, h=−4.9t2+ch=-4.9t2+c, where t is time in seconds, and c is the initial height. A student timed the drop at 1.51 seconds.Use this to determine the height from which the ball was dropped, to at least 2 decimal places.
Your car is parked at the high school. After school you take off and travel for 27 km towards lowa City. At this point, you realize you forget your wallet and travel back to Tipton for 15 km before you find your wallet was just on the floor. You turn back and head towards low city for 36 km. What is your displacement?
