A solid metal cube of mass

6.0\,\text{kg}

and volume

2.0\times10^{-3}\,\text{m}^3

is fully submerged in water and then released from rest. What is the magnitude and direction of its initial acceleration? (Take

g = 9.8\,\text{m/s}^2

and water density

\rho_{\text{w}} = 1.0\times10^{3}\,\text{kg/m}^3

.) (a)

6.5\,\text{m/s}^2

upward (b)

4.9\,\text{m/s}^2

downward (c)

6.5\,\text{m/s}^2

downward (d)

9.8\,\text{m/s}^2
