ball has a radius of 2.5 cm a mass of .125 and is rolling across a table with a speed of .547 m/s, this table is 1.04 m off the ground. It rolls to the edge and down a ramp How fast will it be rolling across the floor?

First I found the

**Gravitational Potential Energy**: Ep=mgh

Initial of 1.2753 FInal = 0

THen the

**Linear Kinetic ENergy**: 1/2 mv^2

Initial .0187005625 FInal .0625v^2

**Elastic Potential Energy**: .5k(delta)x^2

0 0

**Rotational Kinetic Energy**: 1/5mv^2

initial .007480225 FInal .025v^2

Now I need to bring them all togther and

__solve the final velocity__.

Is the Sum of the inital energy's = to the SUM of the final energy's?

If that's true then 1.30148075 = .0875v^2

so v = 3.85 m/s

Is that at all right??
