Hot air balloon is ascending straight up at a constant speed

Reference no: EM13552535

A hot air balloon is ascending straight up at a constant speed of 6.90 m/s. When the balloon is 13.0 m above the ground, a gun fires a pellet straight up from ground level with an initial speed of 31.0 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? Enter the answers in the ascending order.
