In the city center, Matsushima had to travel in sequence 280 m north, 220 m east, 360 m north, 300 m west, 120 m south, 60.0 m east, 40.0 m south, 90.0 m west (road construction) and then 70.0 m north. At that point, he stopped to rest. Meanwhile, a curious crow decided to fly the distance from his starting point to the rest location directly ("as the crow flies"). It took the crow 40.0 s to cover that distance. Assuming the velocity of the crow was constant, find its magnitude and direction. 25.

Long John Silver, a pirate, has buried his treasure on an island with five trees, located at the following points: (30.0 m, 20.0 m), (60.0 m, 80.0 m), (10.0 m, 10.0 m), (40.0 m, 30.0 m), and (70.0 m, 60.0 m), all measured relative to some origin, as in Figure P3.62. His ship's log instructs you to start at tree A and move toward tree B, but to cover only one-half the distance between A and B. Then move toward tree C, covering one-third the distance between your current location and C. Next move toward D, covering onefourth the distance between where you are and D. Finally move towards E, covering one-fifth the distance between you and E, stop, and dig. (a) Assume that you have correctly determined the order in which the pirate labeled the trees as A, B, C, D, and E, as shown in the figure. What are the coordinates of the point where his treasure is buried? (b) What if you do not really know the way the pirate labeled the trees? Rearrange the order of the trees [for instance, B(30 m, 20 m), A(60 m, 80 m), E(10 m, 10 m), C(40 m, 30 m), and D(70 m, 60 m)] and repeat the calculation to show that the answer does not depend on the order in which the trees are labeled. Figure P3.62 63. Consider a game in which N children position themselves at equal distances around the circumference of a circle. At the center of the circle is a rubber tire. Each child holds a rope attached to the tire and, at a signal, pulls on his rope. All children exert forces of the same magnitude F. In the case N = 2, it is easy to see that the net force on the tire will be zero, because the two oppositely directed force vectors add to zero. Similarly, if N = 4, 6, or any even integer, the resultant force on the tire must be zero, because the forces exerted by each pair of oppositely positioned children will cancel. When an odd number of children are around the circle, it is not so obvious whether the total force on the central tire will be zero. (a) Calculate the net force on the tire in the case N = 3, by adding the components of the three force vectors. Choose the x axis to lie along one of the ropes. (b) What If? Determine the net force for the general case where N is any integer, odd or even, greater than one. Proceed as follows: Assume that the total force is not zero. Then it must point in some particular direction. Let every child move one position clockwise. Give a reason that the total force must then have a direction turned clockwise by 360/N. Argue that the total force must nevertheless be the same as before. Explain that the contradiction proves that the magnitude of the force is zero. This problem illustrates a widely useful technique of proving a result "by symmetry" by using a bit of the mathematics of group theory. The particular situation is actually encountered in physics and chemistry when an array of electric charges (ions) exerts electric forces on an atom at a central position in a molecule or in a crystal. 64. A rectangular parallelepiped has dimensions a, b, and c, as in Figure P3.64. (a) Obtain a vector expression for the face diagonal vector R1. What is the magnitude of this vector? (b) Obtain a vector expression for the body diagonal vector R2. 65. Vectors A and B have equal magnitudes of 5.00. If the sum of A and B is the vector 6.00^ , determine the angle between A and j B. 66. In Figure P3.66 a spider is resting after starting to spin its web. The gravitational force on the spider is 0.150 newton down. The spider is supported by different tension forces in the two strands above it, so that the resultant vector force on the spider is zero. The two strands are perpendicular to each other, so we have chosen the x and y directions to be along them. The tension Tx is 0.127 newton. Find (a) the tension Ty, (b) the angle the x axis makes with the horizontal, and (c) the angle the y axis makes with the horizontal. ^ Note that R1, ck , and R2 make a right triangle and prove that the magnitude of R2 is a2 b2 c 2 .
