3.8899 3.8708 3.8461 PART II: The sphere pictured to the right floats above the surface of the water at a height that is proportional to the mass of the person inside plus the mass of the sphere material. The height, h, is related to the mass, m, by the following equation: m=P ( 4r +-3rh?) where P is the density of water, 1000 kg/m, and r is the radius of the sphere, 2 m. The mass of the empty sphere material is 12 kg. A battery of tests were run before bringing this fun device to market, including measuring the height of the sphere above water while people of different weights were inside. Download the height data from the Moodle page. It is contained in a file called HW2_data.txt. 7. Using the "load" or "importdata" command, bring the h values into a matrix, and use the "size" command to find out how many data values are present.
