A disk in Figure 1 is resting in a frictionless groove. Draw the free-body diagram of the disk with mass m and calculate the magnitudes of the forces applied by the groove to the disk as functions of m, g (gravitational constant), a, and ß that keeps this disk in static equilibrium.

The mass of a piece of ice is 0.690 kg, density of water = 1.00 \times 103 kg/m3, and density of ice = 917 kg/m 3. What is the buoyant force on the ice floating freely in liquid water? Enter a positive answer if the buoyant force is upward and a negative answer if the buoyant force is downward. N
