# Confusing Sometimes

A solid sphere of mass $$10\text{ kg}$$ and radius $$2\text{ m}$$ comes down an incline of height $$10\text{ m}$$. The incline makes an angle $$45^\circ$$ with the horizontal.

When the sphere is on the level ground, find the greatest integer value of the velocity of the topmost point on the sphere.

Assume no slipping.
