Find the ratio of its kinetic energy to the energy required

Reference no: EM13997353

A spacecraft made of aluminum circles the earth at a speed of 7800m/s .

Part A: Find the ratio of its kinetic energy to the energy required to raise its temperature from 0 ^oC to 560^oC . (The melting point of aluminum is 660 ^oC . Assume a constant specific heat of 910J/(kg.K) .)

Part B: Discuss the bearing of your answer on the problem of the reentry of a manned space vehicle into the earth's atmosphere.
