- QUESTION 2 Which of the following is an accurate statement? O A. It is possible to add a scalar quantity to a vector. O B. Even though two vectors have unequal magnitudes, it is possible that their vector sum is zero. OC. Rotating a vector about an axis passing through the tip of the vector does not change the vector. OD. The magnitude of a vector is independent of the coordinate system used. O E. The magnitude of a vector can be zero even though one of its components is not zero.The magnitude V1 is 6.2 and it points along the negative x axis, while the magnitude V2 is 8.0 and it points at 40 degrees counter clockwise from the positive x axis. A. What are the x and y components of vector V1? B. What are the X and Y components of vector V2? C. Determine magnitude of the sum V1+V2 D. Determine the angle of the sum V1+V2, measured counter clockwise from the positive x axis.1A) Saanich is walking around the campus. Saanich walks 2.4 km north.

- 4. Three players on a reality TV show are brought to the center of a large, flat field. Each is given a meter stick, a compass, a calculator, a shovel, and (in a different order for each contestant) the following three displacements: A-7lm 52.0° west of south B-59m 26.0 north of west C-27m due east The three displacements lead to the point in the field where the keys to a new Porscho are buried. Two players start measuring immediately, but the winner first calculates where to go. What does she caloulate?A flagpole sits at the center of a playground. Initially, a child is located 8.50 m due north of the flagpole. Two minutes later, the child is 6.00 m away from the flagpole in the direction 37.0° south of east. The displacement of the child lies between which two cardinal directions? O South and west O North and east O North and west O South and east3. A pilot is flying to a destination 230 km south of her current position. An air traffic controller tells her that the wind velocity (as seen on the ground) is 37 km/h [E25 °N]. She knows that the plane's speed is 281 km/h. a) Sketch the overall vectors of the plane to the ground, the plane to the air and the air to the ground. Write the equation for the velocity of the plane relative to the ground with the appropriate subscripts. b) Determine the heading of the plane (in what direction must the pilot fly to compensate for the wind?). Show your work. Label your vectors and label x and y components. c) How long will it take her to reach her destination if she goes at constant velocity with the heading you determined above? (Should it take longer or less time than with no wind?) d) How long would it take her to reach her destination if she went at constant velocity and there was no wind'?
