There is a sphere composed of solid plastic (density = 910 kg/m^3) that is completely submerged underwater. When the sphere is attached to a spring (underwater), the spring is stretched by 0.21m relative to equilibrium length (spring constant, k = 2900 kg/s^2). What is the VOLUME of the marker sphere?

A 10cmx10cmx10cm cube of density 650 kg / (m ^ 3) and is submerged in a container filled with water of density 1000 kg / (m ^ 3) . It is initially held at rest by a string which is attached to the bottom of the container, as shown in the figure. When we cut the string, the cube starts moving upwards. Find the initial acceleration of the cube, immediately after it is released. Answer in units of m/s^ 2
