(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A stone is launched straight up by a slingshot. Its initial speed is 20.2 m/s and the stone is 1.40 m above the ground when launched. Assume g = 9.80 m/s2.

Aow high above the ground does the stone rise?

Bow much time elapses before the stone hits the ground?

2. Relevant equations

Y=V_{i}t+ 1/2a_{y}t^{2}

v_{f}^{2}-v_{i}^{2}/a_{y}=T

3. The attempt at a solution

I have tried the first formula with the time from the second and can't get the answer. I have tried everything I can think of and was even working with others at school to try and get this one. I have seen the other problem identical to this listed but I couldnt understand it. Please Help
