Homework Help: Acceleration problem

  1. Sep 13, 2009 #1
    1. The problem statement, all variables and given/known data
    The surface of a table is 0:8 m above the floor. A marble rolls o the edge of the
    table. The acceleration due to gravity at the surface of the earth is g = 10 m=s2.

    2. Relevant equations
    I am not sure about the equation, it was not given.

    3. The attempt at a solution
    a. How much time does the marble take to go from the edge of the table
    to the floor?
    b. The speed the marble rolls is 2 m=s. How far does the marble travel
    horizontally, after it rolls o the table?

    Hi gztiger, welcome to PF

    1) y = yo + vo*t - 1/2*gt^2
    2) Horizontal velocity does not change due to gravity.
