1. A ball is released from rest from the roof of a 10 metre high building. A water
hose is located 12 metres from the base of the building. Water exits the hose at a
height of 1.5 m above the ground with velocity of 15 m/s.
(a) Determine the angle that the hose must be positioned at so that the water strikes
the ball
(b)
What is the height above the ground where the water strikes the ball?
Does the water strike the ball when the water is rising or falling?
(C)
(d)
What is the relative velocity of the water with respect to the ball when they
intersect?
