Q1. A 1.00 kg beaker containing 1.50 kg of oil (density = 916 kg/m3) rests on a scale. A 1.70-kg block of iron is suspended from a spring scale and is completely submerged in the oil. Find the equilibrium readings of both scales.

Q2. A 76 g, 40-{rm cm}-long rod hangs vertically on a frictionless, horizontal axle passing through its center. A 10 g ball of clay travelling horizontally at 2.70 m/s hits and sticks to the very bottom tip of the rod. To what maximum angle, measured from vertical, does rod (with the attached ball of clay) rotate?
