A 2.10-kg hammer is transported to the Moon. The radius of the Moon is 1.74  106 m, its mass is 7.35  1022 kg, and G = 6.67  10-11 N  m2/kg2. How much does the hammer weigh on Earth and on the Moon?
 
  What will be an ideal response?

Question 2

If the mass of a 1.0-kg book could be entirely converted into electrical energy, how many kW  h of energy would that generate? (c = 3.0  108 m/s)
 
  What will be an ideal response?
