Mr. Hammer's Epic Battle with Two Ninjas

[Chasezap]

Homework Statement

Mr. Hammer would rather be a lover than a fighter, but ninjas often make that impossible for him. In one epic battle, Mr. Hammer fought two ninjas while balancing atop a canoe. He finished one of them off with a forearm shiver that sent the first ninja flying with an initial upward velocity of 2.34 m/s. He finished the other with an atomic elbow drop that sent the second ninja falling with an initial downward velocity of 3.11 m/s. Compare the accelerations of the two ninjas while they are in the air.
