- Given the vector techniques you worked on in the lab, answer the follow question: suppose you first walk 12 m in a direction 20° west of north, then 20 m in a direction 40° south of west, then 14 m in a direction 30° east of north, and finally 19 m in a direction 40° east of south. How far are you (as the crow flies) from your starting point, and what is the compass direction (west of south) of a line connecting your starting point to your final position?arrow_forwardSolve the following problem using analytical techniques: Suppose you walk 17.5 m straight west and then 25.5 m straight north. How far are you from your starting point, and what is the compass direction of a line connecting your starting point to your final position? (If you represent the two legs of the walk as vector displacements A and B, as in the figure below, then this problem asks you to find their sum R = A + B. Give the direction in degrees north of west.) magnitude direction B A R A+B=R m ° north of west W N S Earrow_forwardSolve the following problem using analytical techniques: Suppose you walk 18.5 m straight west and then 26.0 m straight north. How far are you from your starting point, and what is the compass direction of a line connecting your starting point to your final position? (If you represent the two legs of the walk as vector displacements A and B, as in the figure below, then this problem asks you to find their sum R = A + B. Give the direction in degrees north of west.)arrow_forward
- You drive 7.50 km in a straight line in a direction 10° East of North. (a) Find the distances you would have to drive straight East and then straight North to arrive at the same point. (This is equivalent to finding the components of the displacement along the East and North directions.) Answer for km EastAnswer for km North (b) Show that you still arrive at the same point if the East and North legs are reversed in order.arrow_forwardYou will be hiking to a lake with some of your friends by following the trails indicated on a map at the trailhead. The map says that you will travel 5.30 miles directly north, then 6.01 miles in a direction 35.0 degrees east of north, then finally 1.10 miles in a direction 15.0 degrees north of east.Assume north to be +y and east to be +xAt the end of this hike, how far will you be from where you started?arrow_forwardusing analytical techniques andchange the second leg of the walk to 25.0 m straight south.(This is equivalent to subtracting B from A —that is, findingR′ = A – B ) (b) Repeat again, but now you first walk25.0 m north and then 18.0 m east. (This is equivalent tosubtract A from B —that is, to find A = B + C . Is thatconsistent with your result?)arrow_forward
- You start on the origin and walk in a strait line to a point that is 10 m east and 25 m north of where you started. From there you walk 3 m west and another 10 m north, Write each location in terms of vectors A and B. Use vector addition as well.arrow_forwardkindly answer it immediately -A cross country skier 7.40 km in the direction 30 degrees west of south, then 2.80 km in the direction 45 degrees north of west, and finally 6 km in the direction 22 degrees east of north. To then return to his starting point, how far and in what direction must he travel? -A person who is 35 ft east of you runs north at 16 ft/s. At what angle north of east would you throw a ball at 60 ft/s groundspeed in order to hit him? -What is the kinetic energy of a 3000 lb automobile which is moving at 30 mi/h?arrow_forwardGg to get to his office from home, greg walks 6 blocks north and then 3 blocks east. after work he meets some friends at a cafe; to get there he walks 3 blocks south and 6 blocks west. all blocks are 660 ft long. what is the straight line diatance from the cafe to his home?arrow_forward
- A sailor in a small sailboat encounters shifting winds. She sails 2.00 km east, next 3.50 km southeast, and then an additional distance in an unknown direction. Her final position is 5.80 km directly east of the starting point (Fig). Find the magnitude and direction of the third leg of the journey. Draw the vector-addition diagram and show that it is in qualitative agreement with your numerical solution.arrow_forwardI need help with a University Physics 1 (Unit Measurement and Vectors) problem with explanations upon it: A spy report about a suspected car reads as follows. "The car moved 2.00 km towards the east, made a perpendicular left turn, ran for 500 m, made a perpendicular right turn, ran for 4.00 km and stopped". Find the displacement of the car (i.e. Magnitude Resultant and Resultant Direction (angle)).arrow_forwardSuppose a person walks so that their displacement is represented by a vector that has a magnitude of 52m (vector A). The direction of that initial displacement is 31 degrees north of east. After that, the person then walks 15 m due west (vector B). Use trig to calculate the east and north components of the first displacement, vector A.arrow_forward
