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 $\text{10}^{9} \textrm{ }\text{kg}$ meteor moving at 25.0 km/s? (b) If this meteor lands in a deep ocean and $\text{80}\%$ of its kinetic energy goes into heating water, how many kilograms of water could it raise by $5 . \text{0}º\text{C}?\text{ }$ (c) Discuss how the energy of the meteor is more likely to be deposited in the ocean and the likely effects of that energy.
