Question

A balloon carrying a basket is decending at a constantvelocity of 20.0 m/s. A person in the basket throws a stone withthe intial velocity of 15.0 m/s horizontally perpendicular to thepath of the descending ballon, and 4.00s later this person sees therock strike the ground. A. How high was the balloon when the rock was thrownout. Answer h= _____________ m.....I thought I was using theright calulations but my answer is wrong! I came up with98.4. Part C... At the instant the rock hits the ground, how far isit from the basket. Answer d= _____________m. I found the answers to the other questions but these two arestumping me!!

Explanation / Answer

Distance rock falls   h = vy t + 1/2 gt2 = 20 * 4 + 1/2 * 9.8 * 42 = 158.4 m(height when rock thrown) While rock is falling balloon descends   s =vy t = 20 * 4 = 80 m When rock lands it is 158.4 - 80 = 78.4 m Horizontal distance rock travels x = vx t =15 * 4 = 60 m
