25. A car is being compacted into a rectangular solid. The volume is decreasing at a rate of 2 m³/sec. The length and width of the compactor are square, but the height is not the same length as the length and width. If the length and width walls move toward each other at a rate of 0.25 m/sec, find the rate at which the height is changing when the length and width are 2 m and the height is 1.5 m.

26. A rocket is launched into space; its kinetic energy is given by [latex]K(t)=(\frac{1}{2})m(t)v(t)^2[/latex], where [latex]K[/latex] is the kinetic energy in joules, [latex]m[/latex] is the mass of the rocket in kilograms, and [latex]v[/latex] is the velocity of the rocket in meters/second. Assume the velocity is increasing at a rate of 15 m/sec² and the mass is decreasing at a rate of 10 kg/sec because the fuel is being burned. At what rate is the rocket’s kinetic energy changing when the mass is 2000 kg and the velocity is 5000 m/sec? Give your answer in mega-Joules (MJ), which is equivalent to [latex]10^6[/latex] J.

28. An airline sells tickets from Tokyo to Detroit for [latex]$1200[/latex]. There are 500 seats available and a typical flight books 350 seats. For every [latex]$10[/latex] decrease in price, the airline observes an additional five seats sold. What should the fare be to maximize profit? How many passengers would be onboard?
