Increase in temperature of earth due to impact of Theia.

The final stage of the accretion of the Earth involved a giant impact between the proto-Earth and a Mars-sized object, known as Theia. If the final impact velocity was 10000ms-1 calculate the maximum temperature rise in the Earth if all the heat generated by the giant impact was spread rapidly and uniformly throughout the whole planet. Assume the final mass
24
of the Earth is 6 x 10 kg and the mass of Theia 0.1 times that of the Earth. Give your answer to 1 significant figure.
7
As far as I can tell the accretion rate is 10 kg y-1

Solution Summary

The increase in temperature of the the earth due to impact of Theia, a massive object. The solution contains the conservation of momentum and the loss in kinetic energy.
