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/s2). How much work do you do on the aluminum sphere if you raise it from the floor to a height of 2.1 m?
