Randall D. Knight — Fluids and Elasticity: Problem Problem_54

A plastic “boat” with a \(25 \text{ cm}^2\) square cross section floats in a liquid. One by one, you place 50 g masses inside the boat and measure how far the boat extends below the surface. Your data are as follows: Mass added (g) | Depth (cm) --- | --- 50 | 2.9 100 | 5.0 150 | 6.6 200 | 8.6 Draw an appropriate graph of the data and, from the slope and intercept of the best-fit line, determine the mass of the boat and the density of the liquid.
