Two identical rubber balls are dropped from different heights. Ball 1 is dropped from a height of 181 feet, and ball 2 is dropped from a height of 238 feet. Write a function for the height of each ball.
h1(t) = -16t^2 + 181
h2(t) = -16t^2 + 238
When does ball 1 reach the ground? Round to the nearest hundredth. seconds
Solve: -16t^2+181 = 0
-16t^2 = -181
t^2 = 11.3125
t = 3.3634 seconds
-----------------
When does ball 2 reach the ground? Round to the nearest hundredth. seconds
I'll leave this to you.
