# Ball thrown in the air, calculate time to hit the ground.

Hi everyone! First post here, seems like a great community. Anyways, I'm having a bit of trouble.

(I missed a bit of classes due to illness, and I'm a bit behind.)

Here's the problem:

You stand on top of a building 9.50 meters high, and throw a ball almost straight up. The ball is released with an initial velocity of 25m/s [up]. If you release the ball from 2.5m above the top of the building, find the time it takes for the ball to land on the ground.
