Direction of Velocity

  1. Oct 26, 2009 #1
    A glass is slid across a table, goes off the edge and falls to the floor. The table is 0.860m high and the glass lands 1.53m from the edge.
    a) With what velocity did the glass leave the table?

    I found this to be vxi=3.65

    b)What was the directionof the glass's velocity (degrees clockwise from the horizontal) as it hit the ground?

    I used the equation t-1(0.860/1.53) =29.3 but the correct answer is 48.3

    What did I do wrong?

    You need to find the x and y components of the velocity just before the glass hots the floor and calculate the angle from that.
