A hot air ballo0n is ascending straight up at a constant speedof 7.0 m/s. When the balloon is 12.0 m above the ground, agun fires a pellet straight up from ground level with an initialspped of 30.0 m/s. Along the paths of the ballon and thepellet, there are two places where each of them has the altitude atthe same time. How far above ground level are these places?
