A 75 g autographed baseball slides off of a

1.3 m high table and strikes the floor a hori-

zontal distance of 0.65 m away from the table.

The acceleration of gravity is 9.81 m/s2 .

What was the direction of the ballâ€™s velocity

just before it hit the floor?

That is, at what angle (in the range −90◦ to

+90◦ relative to the horizontal directed away

from the table) did the ball hit the floor?

Answer in units of ◦.
