Baseball Projectile Motion

  1. Nov 1, 2009 #1
    1. The problem statement, all variables and given/known data

    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

    2. Relevant equations

    3. The attempt at a solution

    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.
