-  * **Expected Answer:**  The water exerts no force resisting the shark's recoil. That gravity doesn't accelerate the steel ball its way from the catapult to the shark. That the steel ball experiences no air resistance. That the clay ball hits the catapult perpendicular to its arm. That the shark-steel ball collision is elastic. +  * **Expected Answer:**  The water exerts no force resisting the shark's recoil.

That the clay ball hits the catapult perpendicular to its arm at the very end of the arm. That the shark-steel ball collision is elastic.
