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.

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?

FIGURE 2-47 Problem 70.
Figure 2-42 shows a simple device for measuring your reaction time. It consists of a cardboard strip marked with a scale and two large dots. A friend holds the strip vertically, with thumb and forefinger at the dot on the right in Fig. 2-42. You then position your thumb and forefinger at the other dot (on the left in Fig. 2-42), being careful not to touch the strip. Your friend releases the strip, and you try to pinch it as soon as possible after you see it begin to fall. The mark at the place where you pinch the strip gives your reaction time. (a) How far from the lower dot should you place the 50.0 ms mark? How much higher should you place the marks for (b) 100, (c) 150, (d) 200, and (e) 250 ms? (For example, should the 100 ms marker be 2 times as far from the dot as the 50 ms marker? If so, give an answer of 2 times. Can you find any pattern in the answers?)
