Vector B points at an angle of 60.0° above the +x axis and has a magnitude of 200.0 units. Vector C points along the +x axis and has a magnitude of 150.0 units. Which vec- tor has (a) the largest x component and (b) the largest y component? 29. Given the vectors P and0 shown on the 30.0 T8.00 cm grid, sketch and calculate the magnitudes of the vectors (a) M = P +Q and (b) K =2P - Q. Use the tail-to-head method and express the magnitudes in centimeters with the aid of the grid scale shown in the drawing. A, 36. Soccer player #1 is 8.6 m from the goal (see the drawing). If she kicks the ball directly into the net, the ball has a displacement labeled A. *30. mmh Vector A has a magnitude of 12.3 units and points due west. Vector B points due north. (a) What is the magnitude of B if A + B has a magnitude of 15.0 units? (b) What is the direction of A + B relative to due west? (c) What is the magnitude of B if A – B has a magnitude of 15.0 units?

Net If, on the other hand, she first kicks it to player #2, who then kicks it into the net, the ball undergoes two successive displacements, A, and A,. What are the magnitudes and directions of A, and A,? 90 #2 A Problem 36 *31. ssm A car is being pulled out of the mud by two forces that are ap- plied by the two ropes shown in the drawing. The dashed line in the draw- ing bisects the 30.0° angle. The magnitude of the force applied by each rope is 2900 newtons. Arrange the force vectors tail to head and use the graphical technique to answer the following questions. (a) How much force would a single rope need to apply to accomplish the same effect as the two forces added together? (b) How would the single rope be directed 37. Go The components of vector A are A, and A, (both positive), and the angle that it makes with respect to the positive x axis is 0. Find the angle 0 if the components of the displacement vector A are (a) A, = 12 m and A, = 12 m, (b) A, = 17 m and A, = 12 m, and (c) A, = 12 m and A, = 17 m. relative to the dashed line? 38. During takeoff, an airplane climbs with a speed of 180 m/s at an angle of 34° above the horizontal. The speed and direction of the airplane constitute a vector quantity known as the velocity. The sun is shining directly overhead. How fast is the shadow of the plane moving along the ground? (That is, what is the magnitude of the horizontal component of the plane's velocity?) 2900 newtons 30.0° 2900 newtons *32. Go A jogger placement A of 2.50 km due south, and the second involves a displace- ment B that points due east. (a) The resultant displacement A + B has a magnitude of 3.75 km. What is the magnitude of B, and what is the direction of Ã + B relative to due south? (b) Suppose that A – B had a magnitude of 3.75 km. What then would be the magnitude of B, and what is the direction of A – B relative to due south? 39. ssm The x vector component of a displacement vector ř has a mag- nitude of 125 m and points along the negative x axis. The y vector compo- nent has a magnitude of 184 m and points along the negative y axis. Find the magnitude and direction of F. Specify the direction with respect to the negative x axis. 40. Your friend has slipped and fallen. To help her up, you pull with a force F, as the drawing shows. The vertical component of this force is 130 newtons, and the horizon- tal component is 150 newtons.
