A 1.13 kg hollow ball with a radius of 0.139 m, filled with air, is released from rest at the bottom of a 1.86 m deep pool of water. How high above the water does the ball shoot upward? Neglect all frictional effects, and neglect the ball's motion when it is only partially submerged.

never mind. i got it.
u would find the acceleration to find velocity of the ball coming out of the water and then, use kinematics to find the height.
I'm kind of confused about this question... so to figure out the accleration you would do F= Fb -w where Fb is the buoyancy force and F is the net force. THen you would you F=ma to find the accleration...but after that I'm kind of lost...helpp pleaseee..
