You are on the street trying to hit a friend in his dorm window with a water balloon. He has a similar idea and is aiming at you with his water balloon. You aim straight at each other and throw at the same instant. Do the waterballoons hit each other? Explain why or why not
3) A hot air balloon with a basket descends with a constant downward velocity of VB = 20m/s. A stone of mass
ms = 1.0kg is thrown from the basket with an initial velocity of vo= 15m/s perpendicular to the path of the
descending balloon, as measured relative to a person at rest in the basket. That person sees the stone hit the
ground t = 10s after it was thrown. Assume that the balloon continues its downward descent with the same
constant speed of VB = 20m/s.
a) How high was the balloon when the rock was thrown out?
How high is the balloon when the rock hits the ground?
b)
c) At the instant the rock hits the ground, how far is it from the basket?
