A person driving her car at 35 km/h approaches an inter- section just as the traffic light turns yellow. She knows that the yellow light lasts only 2.0s before turning to red, and she is 28 m away from the near side of the intersection (Fig. 2–49). Should she try to stop, or should she speed up to cross the intersection before the light turns red? The intersection is 15 m wide. Her car's maximum deceleration is -5.8 m/s?, whereas it can accelerate from 45 km/h to 65 km/h in 6.0 s. Ignore the length of her car and her reaction time. – 28 m - -15 m→ FIGURE 2-49 Problem 73.

In putting, the force with which a golfer strikes a ball is planned so that the ball will stop within some small distance of the cup, say 1.0m long or short, in case the putt is missed. Accomplishing this from an uphill lie (that is, putting the ball downhill, see Fig. 2–47) is more difficult than from a downhill lie. To see why, assume that on a particular green the ball decelerates constantly at 1.8 m/s² going downhill, and constantly at 2.6 m/s² going uphill. Suppose we have an uphill lie 7.0 m from the cup. Calculate the allowable range of initial velocities we may impart to the ball so that it stops in the range 1.0 m short to 1.0 m long of the cup. Do the same for a downhill lie 7.0 m from the cup. What in your results suggests that the downhill putt is more difficult? Uphill lie Downhill 7.0 m lie - 7.0 m FIGURE 2-47 Problem 70.

An initially stationary hovercraft sits on a large lake. Whena whistle blows the hovercraft accelerates due north at a rate of1.2 m s−2for 10 s, does not accelerate at all for the next 10 s, andthen accelerates at a rate of 0.6 m s−2 due east for another 10 s. Thehovercraft then coasts for another 10 s without any acceleration.(a) What is the velocity of the hovercraft 40 s after the whistleblows?(b) What is the displacement of the hovercraft 40 s after thewhistle blows?
