a bowling ball with a mass of 5.45kg and a radius of .191m starts from the rest at a height of 1.8m and rolls down a 22.3m slope. what is the translational speed of the ball when it leaves the incline.

**2. Homework Equations**

E=mgh +1/2mv^2+1/2Lw^2

**3. The Attempt at a Solution**

E=5.45kg*9.81m/s*1.8m+ 1/2 %.45kg* v^2+1/2 Lw^2

???is this even right?
