A ball was thrown straight down from a bridge at 20.0 m/s and it hit the water below the bridge 1.50 seconds after its release. (Include a labeled diagram showing this information.)
a) 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.)
b) 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.)
c) What was the stone's speed just before it hit the water.
d) What was the magnitude of the stone's velocity just before it hit the water.
