A wooden ball with a weight of 18.0 N hangs from a string tied to a spring scale. When the ball is at rest, exactly 50% submerged in water, the spring scale reads 6.00 N. For this problem, we will use a density of water of 1000 kg/m3, and we will use g = 10.0 m/s2. 1. If the ball was only 20.0% submerged in water instead, what would the spring scale read? 2. Determine the density of the ball. 3. Determine the volume of the ball.
