Question
A golf ball is thrown from the top of a cottage roof with an initial velocity
of 11.0 m/s at 56.0° above the horizontal. Just as it reaches the ground, the vertical component
of the golf ball's velocity is measured to be 13.5 m/s downwards. (The solution you submit for
this TEST PROBLEM must be entirely your work only.)
(a) What must the height
of the cottage roof?
(b) How far horizontally will the
ball have moved when it has
reached the peak of its trajectory?
