What is the equation used to represent the height of the coin in the fountain problem?

• h(t) = -16t^2 + 7t + 4

• h(t) = 16t^2 - 7t + 4

• h(t) = -16t^2 - 7t + 4

• h(t) = 16t^2 + 7t + 4

How long did it take for the coin to land at the bottom of the fountain?

• 0.50 seconds

• 1.00 seconds

• 0.33 seconds

• 0.77 seconds
