A ball is thrown straight up from a bridge at 20.0 m/s. The ball reaches its maximum height, falls, just misses the bridge on the way down, and hits the water below the bridge 4.80 seconds after its release. (Include a labeled diagram showing this information.)
a) How long after its release did the ball reach its maximum height? (Include any formulas/equations used, show your substitution into any formula/equation used, and show the answer resulting from your substitution into any formula/equation used.)
b) How high above the bridge did the ball rise? (Include any formulas/equations used, show your substitution into any formula/equation used, and show the answer resulting from your substitution into any formula/equation used.)
c) How high was the bridge? (Include any formulas/equations used, show your substitution into any formula/equation used, and show the answer resulting from your substitution into any formula/equation used.)
d) Calculate the stone's velocity just before it hit the water. (Include any formulas/equations used, show your substitution into any formula/equation used, and show the answer resulting from your substitution into any formula/equation used.)
