Consider a car moving at highway speed u. Is its actual kinetic energy larger or smaller than 1/2 mu2? Make an order-of-magnitude estimate of the amount by which its actual kinetic energy differs from 1/2 mu2. In your solution, state the quantities you take as data and the values you measure or estimate for them. You may find Appendix B.5 useful.
