Question

A tabletop gamer has designed a game that requires three dice to be thrown onto a tray with a measurement grid. To add an extra degree of randomness, the coordinates of the center of mass of the three dee are used as well. The mases of the three dice are 11. 9 g. 15. 5 g. and 18 1 g. and their respective coordinates after one particular throw are (0. 475 m. -0. 471 m). (-0. 383 m. 0. 111 m). and (-0437 m. -0319 m). What are the resulting coordinates of the center of mass of the dice, Xom, and yom?

Explanation / Answer

Xcm=(m1x1+m2x2+m3x3)/(m1+m2+m3)

      =(11.3 *0.475-15.5*0.383-18.1*0.437)/(11.3+15.5+18.1)

      =-8.4787/44.9=0.1888m

Ycm=(m1y1+m2y2+m3y3)/(m1+m2+m3)

      =(-11.3 *0.471+15.5*0.111-18.1*0.391)/(11.3+15.5+18.1)

      =-0.2378m
