Homework Statement



A 72 g autographed baseball slides off of a
1.3 m high table and strikes the floor a hori-
zontal distance of 0.7 m away from the table.
The acceleration of gravity is 9.81 m/s2 .

What was the direction of the ball’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 degrees

Hi lev1234! Welcome to PF! :smile:

The ball slides off the table, so its initial velocity is horizontal.

Treat movement in the x and y directions separately.
