Rolling ball
Since we’re not interested in direction or time, we’ll use Conservation of Energy.
We know that for a ball (sphere), I = (2/5)mr2.
We know that KEregular = (1/2)mv2 .
We know that KErotational = (1/2)Iw2.
We know that PEgravity = mgh .
We know that without slipping, even though friction causes the ball to roll, there is no Elost because the fall does not slide.
