- 2.) Anthony joined a challenge game in his school. To get to the clue, he has to walk 30 meters 30° North of East, 20 meters 60° North of West and finally 10 meters toward Southwest. How far and in what direction is the clue from Anthony's original position?(please solve within 15 minutes I will give thumbs up thanks)Two siblings (Lisa and Bart) drive away from home. Lisa drives 100 miles due North. Bart drives 50 miles due South and then 50 miles due East.

- You fly 35.0 km in a straight line in still air in the direction 31.0° south of west. a) Find the distances you would have to fly straight south and then straight west to arrive at the same point. 18.0263 30.0009 30.0792 km South b) Find the distances you would have to fly first directly south-west and then directly north-west. 7.49958 km West km South-West km North-West13) While hiking, you travel 5.0 miles south (vector Ā), then turn and travel 4.0 miles at an angle of 30 degrees north of east (B). a) Sketch a diagram of these two displacement vectors, roughly to scale. Assume the positive x-axis is in the east direction, and the positive y-axis is in the north direction. b) You now wish to return to where you started. Determine the magnitude and direction of the displacement vector Ď you must follow. Use the method of components. As always, show all the details of your work. (Show vector D in the diagram above.) (Use clear, standard notation; show all details of your work. See PSL 3.4-5.)1
- 2. An airplane flies with a displacement vector r. If the x-component of the plane is 132 km West and the y-component of the plane is 129 km South, what is the magnitude and direction of the resultant vector r? (Specify the direction with respect to the negative x axis).In U.S. football, after a touchdown the team has the opportunity to earn one more point by kicking the ball over the bar between the goal posts. The bar is 10.0 ft above the ground, and the ball is kicked from ground level, 36.0 ft horizontally from the bar (the figure (Figure 1)). Football regulations are stated in English units, but convert to SI units for this problem. If the ball is kicked at 37 above the horizontal, what must its initial speed be if it to just clear the bar? Express your answer in m/s. If the ball is kicked at 37 above the horizontal, what must its initial speed be if it to just clear the bar? Express your answer in km/h.26. A map suggests that Atlanta is 730 miles in a direction of 5.00° north of east from Dallas. The same map shows that Chicago is 560 miles in a direction of 21.0° west of north from Atlanta. Modeling the Earth as flat, use this informa- tion to find the displacement from Dallas to Chicago.
