Normally I do all my Physics homework at school, so I can ask the teacher for assistance any time. But I have these last two problems left, and can't find the notes for the equations. Here are the two problems.
Someone is standing on a 50.0 m cliff over a lake. He throws 2 stones vertically 1 sec apart and they hit the water at the same time. The 1st stone had a initial v of 2.0 m/s. How long does it take for the stones to hit the water? Intial v of 2nd stone? What will the velocities of each stone be when they hit? (The exact momennt that they hit)
Second problem- A rocket goes straight up with initial speed of 50.0 m/s. It accelerates up 2.00 m/s squared. It stops at 150 m. What is the max height it reaches? When does it get there? For how long is it in the air?
I appreciate any assistance you can give me on this one, whether it's just some equations or the answers. Thanks!
