Chapter 14, Problem 67PE

Integrated Concepts

Large meteors sometimes strike the Earth, converting most of their kinetic energy into thermal energy. (a) What is the kinetic energy of a $\text{1}{0}^{\text{9}}\text{kg}$ meteor moving at $\text{25}.0\text{ km}/\text{s}$ ? (b) If this meteor lands in a deep ocean and 80% of its kinetic energy goes into heating water, how many kilograms of water could it raise by $\text{5}.0°\text{C}$ ? (c) Discuss how the energy of the meteor is more likely to be deposited in the ocean and the likely effects of that energy.
