Answer

Jeremy is correct that Micah just needs to throw balls away from himself.

Work Step by Step

Jeremy is correct that Micah just needs to throw balls away from himself. We can assume that the initial momentum of the system of Micah, the skateboard, and the balls is zero. If Micah gives the balls a momentum in the direction of the wall, by conservation of momentum, Micah and the skateboard must gain the same magnitude of momentum in the opposite direction.
