- Imagine that the y-axis points north and the x-axis points east. (a) If you travel a distance r = 22 km in a straight line from the origin in a direction 35 degrees south of west, what is your position in Cartesian (x,y) coordinates? (b) If you travel 6 miles due south from the origin and then turn west and travel 2 miles, how far from the origin and in what direction is your final position?for this problem the average distance of the earth from the sun is about 1.5×10^8kmIt takes the Earth approximately 365 normal days to orbit the sun. Using this information and assuming 24 hours in a normal day, approximately how many nanoseconds does it take for the Earth to orbit the sun?
- You leave your home and walk 2 km at an angle 60° north of east (i.e. your direction is 60° if east is +x and north is in the +y direction). Then you walk 1 km due south. How far east of your home are you? Group of answer choices 1 km (√3) km 3 km (√3)/2 km 2 kmA map suggests that Atlanta is 730 miles in a direction 5.00° north of east from Dallas. The same map shows that Chicago is 560 miles in a direction 21.0° west of north from Atlanta. The figure below shows the location of these three cities. Modeling the Earth as flat, use this information to find the displacement from Dallas to Chicago. magnitude = mi direction = ° north of east of DallasTwo yachts started from the same port at the same time. Yacht A sails at a velocity of 9 miles per hour 34°46’7’’ due west and Yacht B sails at a velocity of 6 miles per hour 25°13’53’’ due east. After 40 minutes, how far apart are they from each other?
