A glass is slid across a table top, goes of the edge and falls to the floor below. The table is 0.860 m high and the glass lands 1.77 m from the edge.
(a) With what velocity (m/s) did the glass leave the table top?
(b) What was the direction of the glass's velocity (degrees clockwise from the horizontal)as it hit the ground?
