A $0\mathrm{.}200$ kg clay ball moving to the right at $8\mathrm{.}0$ m$/$s catches up and collides with a $0\mathrm{.}600$ kg clay ball moving at $2\mathrm{.}0$ m$/$s directly upward. The two clay balls stick together after the collision. Show your work. What is the magnitude of their final velocity vector? $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$ What angle does their final velocity vector make with the horizontal? $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$
