a hot-air balloon having initial velocity vi as it ascends. Then, a water balloon is dropped from the basket when it is 135 meters high and would hit the ground after 9.00 seconds. a) find the velocity of the hot-air balloon upon release of the water balloon.

The person in the basket fears for the safety of those below and yells out a warning. The speed of sound is 343 m/s. b)assuming he can be heard from this height, how long does it take for the warning to reach the ground?

After hearing the warning, a bystander decides to take matters into his own hands and shoots the water balloon with an arrow.

c) if the arrow has an initial velocity of 50m/s straight up at what elevation does arrow strike the water balloon?
