Thor stands on the top of Stark Tower (425 m) and fights his brother Loki using Mjolnir, his hammer. If his hammer has a mass equal to 300 billion elephants (call it 4.5*1015 kg), what is the gravitation potential energy (in J) of Mjolnir, relative to the ground? (Use scientific notation to enter your answer: 1.23E12 means 1.23 * 1012) 2.Loki tricks Thor into dropping Mjolnir off of Stark Tower. When the hammer has fallen one third of the way down the tower, what is its kinetic energy (in J)? (Hint: you could find the speed, then calculate the kinetic energy, but there's an easier way…)
