a) Determine the force required to just submerge a Size 5 soccer ball (assume 9" diameter) in a swimming pool. Neglect the weight of the soccer ball material & air inside. b) Determine the force required to just submerge a 3ft diameter beach ball in a swimming pool. Neglect the weight of the beach ball material & air inside. c) Do the same calculations for submerging the soccer ball and beach ball but this time in a vat filled with mercury. d) Compare the forces and explain your results.
