Large meteors sometimes strike the Earth, converting most of their kinetic energy into thermal energy.

(a) What is the kinetic energy of a 10⁹ kg meteor moving at 25.0 km/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 5.0°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.
