Calculation

Duringthe movie Titanic, Jack and Rose have to try and survive the sinking of the ship. Both of them experience hypothermia, which is when your body temperature lowers to dangerous levels. Assume thatJackhad a mass of90.7 kg andRosehad a mass of68 kg. When they hit the water, both have an initial body temperature of37and after some time, both of their body temperatures lower to a final temperature of28. Thespecific heat capacity for the human body is3470 J/kg

1. What is thethermal energylost byJack?
2. What is thethermal energylost byRose?

For an object about the size and mass of a human, water causes energy to be lost at95,000 J per minute. In air, energy is lost at30,000 J each minute.

1. How muchtimedoes it take forJackto lose that much energy?
2. How muchtimedoes it take forRoseto lose that much energy?
