Answer #1

Density of copper = 8.92 gm/cm3

mass of copper = 87.2gm

volume of copper = mass/density

                        = 87.2/8.92 = 9.77cm3

edgelength a3 = v

                 a = V1/3

                    = (9.77)1/3 = 2.13 cm

There is a cube of length c. It is in unstable equilibrium, balanced on its edge. The cube is at rest on frictionless surface A. A small shock, or impulse, causes the cube to escape the equilibrium point and topple. After the cube is toppled, the cube is under uniform gravitational field, meaning that g is constant. The cube rotates until any part of it hits the table. Before the cube hits the table, what is the cube's final angular...
