Solving Acceleration Problem: Time & Distance Calculations

[gztiger]

Homework Statement

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.

Homework Equations

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

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 PF1) y = yo + vo*t - 1/2*gt^2
2) Horizontal velocity does not change due to gravity.
