How high was the balloon when the rock was thrown out? A 124-kg balloon carrying a 22-kg basket is descending with a constant downward velocity of 22.0 m/s A 1.0-kg stone is thrown from the basket with an initial velocity of 14.6 m/s perpendicular to the path of the descending balloon, as measured relative to a person at rest in the basket. The person in the basket sees the stone hit the ground 7.30 s after being thrown. Assume that the balloon continues its downward descent with the same constant speed of 22.0 m/s.

Constants According to the Guinness Book of World Records, the longest home run ever measured was hit by Roy "Dizzy Carlyle in a minor league game. The ball traveled 188 m (618 ft) before landing on the ground outside the ballpark. Part A You may want to review (Page). For help with math skills, you may want to review: Assurning the ball's initial velocity was 40° above the horizontal and ignoring air resistance, what did the initial speed of the ball need to be to produce such a home run if the ball was hit at a point 0.9 m (3.0 ft) above ground level? Assume that the ground was perfectly flat. Express your answer using two significant figures. Solving Quadratic Equations View Available Hint(s) Vector Magnitudes Resolving Vector Components AEQO 2 ?
