To float weight of body = weight of fluid displaced by it
Mg = mg
m= density of fluid x Volume of object = 1025 x 6.97 x 9.8= 70013.65
Mg= 70013.65
M= mass of bear + mass of ice
Mass of ice= density of ice x volume of ice = 917x 6.97 = 6391.49
So (mass of bear + mass of ice)g = 70013.65
Mass of bear = 752.76kg
Weight= 7377N
