You are on a 5 m high roof and throw a ball upwards at 10 m/s. It lands on the ground below you.
a. How long was it in the air?
b. What is its final velocity?
The answers are suppose to be 2.41s, and -14m/s but I am confused on how to solve the problem to get the answers.

1) find the time it takes to reach its max height
2 find the distance to the top height 
3) find the total distance by adding the distance to top + distance of roof from ground
4) now take total distance from top(peak) and add variables needed
5) find time variables and add both values together

Can you tell me the equation to use to find the max height please? I tried to look for it in my formula sheet but I wasn't sure which one to use.
