In the middle of the night you are standing a horizontal
distance of 14.0 m
from the high fence that surrounds the estate of
your rich uncle. The top of the fence is 5.00 m
above the ground.
You have taped an important message to a rock that you want to
throw over the fence. The ground is level, and the width of the
fence is small enough to be ignored. You throw the rock from a
height of 1.60 m
above the ground and at an angle of
52.0
above
the horizontal.
What minimum initial speed must the rock have
as it leaves your hand to clear the top of the fence?
For the
initial velocity calculated in the previous part, what horizontal distance beyond
the fence will the rock land on the ground?
