(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data2 Identical pellet guns are fired simultaneously from the edge of a cliff. These guns impart an initial speed of 30.0 m/s to each pellet. Gun A is fired straight upward, with the pellet going up the cliff and then falling back down, eventually hitting the ground beneath the cliff. Gun B is fired straight downward. In the absence of air resistance, how long after pellet B hits the ground does pellet A hit the ground.

a= 9.8 m/s^2

Vo=30.0 m/s

t=?

2. Relevant equations

y=Vot + 1/2 at^2

or t=Vo*2/a

v=Vo + at

3. The attempt at a solution

Here is what I did. 30.0 m/s *2/9.8 m/s^2= 6.12 s. The answer is right, but did I do the problem right.
