A rocket burns up at the rate of 5 tons/min after falling out of orbit into the atmosphere. If the rocket weighed 5400 tons before reentry, express its weight w as a function of the time t, in minutes, of reentry. Write the weight of the rocket as the function w(t). w(t)=\boxed{} (Simplify your answer. Do not factor.)

4. Ozone (O3) in the lower troposphere is primarily created by the photolysis of nitrogen oxides following the equilibrium equation shown below. Why is the concentration of ozone typically higher in the air of big cities than what is predicted based on the stoichiometry of the equation below? No need to provide chemical equations, but clearly explain the underlying mechanism, including any additional pollutants that play a role in this process and their sources. (6 points) $NO_2 \overset{k_f}{\underset{k_b}{\rightleftharpoons}} NO + O_3$ $k_f = 0.009 \text{ s}^{-1}$ $k_b = 1.8x10^{-14} \text{ cm}^3 \text{ molecule}^{-1} \text{ s}^{-1}$
