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?
