A ping pong ball is a hollow air-filled sphere one such, Ask an Expert

Academics

A Ping Pong ball is a hollow, air-filled sphere. One such Ping Pong ball has a radius of 2.25 cm and a mass of 3.5 g. When the ball is placed a few centimeters below the surface of body of fresh water and released, the ball will accelerate upwards

a) Determine the acceleration of the ball the moment when it is released.
b) If the ball is pushed further down into the water, it will eventually reach equilibrium. That is, at some depth, when released, the ball will not try to float upward nor try to sink. Determine this depth.
