Express your answer to three significant figures and include the appropriate units.

Explanation / Answer

Mass of each coin m1 = m2 = m3 = m

Coordinates are m1( 0,0 ) , m2( 15,0) , m3( 0,15)

X-coordinate of the center of gravity of the threecoins = [ m*0+m*15+m*0 ] / ( m+ m+ m)

                                                                                  = 15m/3m

                                                                                  = 5 cm

Y-coordinate of the center of gravity of the threecoins = [ m*0+m*0+m*15 ] / ( m+ m+ m)

                                                                                  = 15m/3m     

                                                                                  = 5 cm

Coordinates of center of gravity are (5 cm, 5 cm)
