I am working on a problem which I'm confused about. I think I know how to do vertical motion downward but I'm not sure what to do about upward. The problem is : A person standing on a creek bed throws a rock straight up at a speed of 64 feet per second.
1) When will the rock reach a maximum height?
2) When would the rock hit the water again?
I know the formula for vertical motion is h=-16t^2+vt+s
When I did a problem throwing something down from a bridge I put the height at o because I was throwing downward. Could someone please help me on how I get started with the equation going upward?
