Chapter 7, Problem 58GP
CE Predict/Explain A car is accelerated by a constant force, F. The distance required to accelerate the car from rest to the speed u is Δx. (a) Is the distance required to accelerate the car from the speed u to the speed 2u equal to, 2Δx, 3Δx or 4Δx? (b) Choose the best explanation from among the following
- I. I. The final speed is twice the initial speed.
- II. II. The increase in speed is the same in each case.
- III. III. Work is force times distance, and work depends on the speed squared.

- 1.62 On a training flight, a Figure P1.62 student pilot flies from Lincoln, Nebraska, to Clarinda, Iowa, next to St. Joseph, Missouri, and then to Manhattan, Kansas (Fig. P1.62). The directions are shown relative to north: 0° is north, 90° is east, 180° is south, and 270° is west. Use the method of components to find (a) the distance she has to fly from Manhattan to get back to Lincoln, and (b) the direction (relative to north) she must fly to get there.

In a carnival booth, you can win a stuffed gi- raffe if you toss a quarter into a small dish. The dish is on a shelf above the point where the quarter leaves your hand and is a horizontal dis- tance of 2.1 m from this point (Fig. E3.19). If you toss the coin with a velocity of 6.4 m/s at an angle of 60° above the horizontal, the coin will land in the dish. Ignore air resistance.
