youtube.com/watch?v=srDeACrSf-o&t=12s     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.
