A rock is dropped from a balloon that is moving horizontally. The rock stays in the air for 3 s before it reaches the ground with its trajectory making an angle of 30? from the vertical. What is the balloon’s velocity? With which distance above the ground is the balloon flying? What was the horizontal range of the trajectory? What is the rock’s velocity when it reaches the ground?
