At 11:59:25.00 the cable holding the ball snaps. a ) (6 points) How far above the ground is the ball when the cable snaps? Using a motion diagram or graph here is helpful: the ball falls 30 m in 60 s at a constant rate. Choose a point on the graph or diagram to see that this occurs at (35 / 60) 30 = 17 . 5 m above the ground. Or, solve for v and calculate distance as y 1 = v t , then subtract from total height: 30 m 0 m 0 s 60 s 5 s 1 s after before v = 30 / 60 = 0 . 5m / s y 1 = 0 . 5 25 = 12 . 5m y 2 = 30- 12 . 5 = 17 . 5m b ) (9 points) How much earlier does the New Year begin, according to when the ball hits the ground?...
