1.
Height h = 240 feet
We insert it into formula.
Now we solve this for t:
We have two answers as the rocket will pass this height on it's way up and down.
2.
Height h = 0 feet
We insert it into formula.
Now we solve this for t:
We do not consider solution -1 as the time can not be negative. Our solution is 5s.
3.
Height at bottom of hill h = 0 feet
We insert it into formula.
Height h = 240 feet
We insert it into formula.
Now we solve this for t:
We have two answers as the rocket will pass this height on it's way up and down.
2.

We insert it into formula.
Now we solve this for t:
We do not consider solution -1 as the time can not be negative. Our solution is 5s.
