FRQ prompt

Free Response:
A 0.050 kg glass marble is dropped from rest into a tank of water (density 1000 kg/m³). The marble has radius 1.0 cm and density 2500 kg/m³.

(a) Calculate the buoyant force on the fully submerged marble.
(b) Calculate the net force on the marble when fully submerged. Does the marble sink or float? Explain.
(c) If instead the marble were hollow with the same outer radius but total mass 0.010 kg, determine whether it would sink or float and justify your answer.
