# Waxed

Classical Mechanics Level 2

Two sticky balls of wax (perfectly inelastic) are placed on a frictionless surface.

One has a mass of $$20 \text{ g}$$ and is sent due East at a speed of $$2 \text{ cm/sec}$$.

One has a mass of $$10 \text{ g}$$ and is sent due West at a speed of $$1\text{ cm/sec}$$.

When they collide head-on and stick together, what direction and speed will the final $$30\text{ g}$$ ball of wax have?
