Ben Toocloze is being chased through the woods by a bull moose which he was attempting to photograph. The enormous mass of the bull moose is extremely intimidating. Yet, if Ben makes a zigzag pattern through the woods, he thinks he will be able to use the large mass of the moose to his own advantage. Explain this using the terms inertia and mass in your explanation why this is a great option or poor option for Ben Toocloze.
