A ball is projected horizontally from the edge
of a table that is 1.2 m high, and it strikes the
floor at a point 1.11 m from the base of the
table.The acceleration of gravity is 9.8 m/s2 .How high is the ball above the floor when its
velocity vector makes a −54.3153� angle with
the horizontal?
Answer in units of m
