1. An asteroid made out of iron (7860 kg/m3) strikes the Earth in an area where the oceans are very deep. The velocity of the asteroid upon impact is the same for most debris hitting the Earth's atmosphere, 30 km/s. The difference in potential energy from orbit to ground is negligible at this speed. Assuming that 80% of the asteroid's kinetic energy is transferred to heating the water, what volume of water (assuming a density of 1000 kg/m3) will be vaporized? We will assume that the water is taken from 70 F to the point that it becomes steam. Also, assume that the asteriod is spherical, with a radius of 750 m
