Two identical rubber balls are dropped from different heights. Ball 1 is dropped from a height of 100 feet, and ball 2 is dropped from a height of 210 feet. Write a function for the height of each ball.
h1(t) =
h2(t) =
When does ball 1 reach the ground? Round to the nearest hundredth. _____seconds
When does ball 2 reach the ground? Round to the nearest hundredth. _____seconds

algeba 1 please I REALY NEED HELP THANK YOU :D 
Steve,
his is quite similar to the rocket problem. You should know the equation for height of a projectile. Just use it to solve for t when the height is zero.
How far do you get? Where do you get stuck? "I have no idea" is not a useful attempt at a solution.
