Homework Help: Physics

Posted by Anonymous on Friday, January 2, 2009 at 10:44pm.

A hot air balloon is ascending straight up at a constnat speed of 7.0 m/s. When th balloon is 12.0 m above the ground, a gun fires a pellet straight up from ground elvel with an initial speed of 30,0 m/s. Along the paths of the balloon and the pellet, there are two places where each of them has the same altitude at the same time. How far above ground level are these places?

I'm thinking I should be setting two kinematics equations equal to each other, but I don't know which ones.
