Calculate the mass of each sphere:

You may want to reference (Pages 15 - 16) Section 1.4 while completing this problem.

Consider the two spheres shown here, one made of silver and the other of aluminum.

The force of gravity acting on an object is F = mg, where m is the mass of an object and g is the acceleration of gravity (9.8 m/s^{2}). How much work do you do on the aluminum sphere
if you raise it from the floor to a height of 2.1
m?
