(b) The asteroid enters earth atmosphere and begins to burn up. Each second it is falling through the atmosphere, the asteroid's velocity will increase (because gravity is pulling it toward the earth) While its mass will decrease (because it is burning up). Let m(t) be the inass of the asteroid t seconds after it enters the atmosphere and v(t) be the velocity of the asteroid t seconds after it enters the atmosphere. Write a formula (in terms of m(t) and v(t) and their derivatives.) E . for the derivative %, the rate of change of kinetic energy with respect to time. dE What are the units of
