Equations include those for linear motion, rotary motion, momentum, energy, etc. This is a great study tool, if a student is capable of understanding and using these formulas they should be able to do well on any exam in this area.

Use the formulas for 'solving a linear differential equation'.
1) Write the equation in standard form y' = P(x)y = Q(x)
2) Find the integrating factor u(x) = e^( ? P(x) dx)
3) Evaluate the integral to find the general solution
y = (1/u(x) ? Q(x) u(x) dx
4) Satisfy whatever initial condition is included.
1) y' + (2x

Two cars with new tires are driven at an average speed of 60 mph for a test drive of 2000 miles. The diameter of the wheels of one car is 15 inches. The diameter of the wheels of the other car is 16 inches. If the tires are equally durable and differ only by diameter, which car will probably need new tires first? Why?

I am pretending that I am interviewing for a position with an association representing the tire industry. The federal government mandates safety testing of all tires manufactured in the United States. Recently there has been concern that the rubber used in the tires could deteriorate while in store inventories. In September
