A 124-kg balloon carrying a 22-kg basket is descending with a constant downward velocity of 20.0 m/s. A 1.0-kg stone is thrown from the basket with an initial velocity of 15.0 m/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 5.00 s after it was thrown. Assume that the balloon continues its downward descent with the same constant speed of 20.0 m/s. (a) How high is the balloon when the rock is thrown? (b) How high is the balloon when the rock hits the ground? (c) At the instant the rock hits the ground, how far is it from the basket? (d) Just before the rock hits the ground, find its horizontal and vertical velocity components as measured by an observer (i) at rest in the basket and (ii) at rest on the ground.

Two children, one at the front of a parade float and one at the back, are playing catch with a ball. Each sees the other as tossing the ball at 4.0 m/s. The float moves down the road at 2.0 m/s. At what speed do the two children toss the ball from the point of view of a spectator watching the float move by?
A ball is thrown vertically upward with a speed of 12.0 m/s inside a bus moving at 9.0 m/s. What is the velocity of the ball as observed by a man standing on the street?
Daniel takes his two dogs, Pauli the Pointer and Newton the Newfoundland, out to a field and lets them loose to exercise. Both
dogs sprint away in different directions while Daniel stands still. From Daniel's point of view, Newton runs due North at 4.65
m/s, but from Pauli's point of view, Newton appears to be moving at 2.10 m/s due East. What must Pauli's velocity relative to
Daniel be for this to be true? Express your answer in terms of the x- and y-components if North is the +y-direction and East
is the +x-direction.
x-component:
m/s
Y-component:
m/s
Express your answer as a magnitude and an angle measured counter-clockwise from due East.
magnitude & direction:
at a angle
counter-clockwise from due East
