Problem

Four solid objects P, Q, R, and S are released from rest at the surface of a large tank of water. Their densities are P:

0.80\,\text{g/cm}^3

0.98\,\text{g/cm}^3

1.00\,\text{g/cm}^3

1.20\,\text{g/cm}^3

Which sequence ranks the objects from greatest initial upward acceleration to greatest downward acceleration? a) Q, P, R, S b) P, Q, R, S c) P, Q, S, R d) S, R, Q, P
