If a Person Drops a Penny (M = 2 $\mu$ K
B)17

If a person drops a penny (m = 2.5 g) off of the top of the Statue of Liberty (h = 46.84 m) and it lands in a water barrel of water (159 kg) .Find the change in temperature of the water,assuming all of the kinetic energy of the penny goes into heating the water.Ignore the effects of air resistance on the penny and the heat capacity of the penny.The specific heat of water is 4.19 kJ/(kg * K) or 1.00 cal/(g * K) .

A) 0.18 $\mu$ K
B) 1.7 $\mu$ K
C) 0.74 mK
D) 7.2 mK
E) None are correct.
