Use the graphical method (drawing the route) to find the magnitude of the jogger's net displacement. a. 14.0 blocks b. 11.0 blocks c.8.0 blocks d. 13.0 blocks 4. An athlete runs 110 m across a level field at an angle of 30.0 north of east. What are the horizontal and vertical components, respectively, of this displacement? a.64 m, 190 m b.95 m, 55 m c. 190 m, 64 m d.55 m, 95 m 5 . A hiker walks 4.5 km at an angle of 45 north of west. Then the hiker walks 4.5 km south. What is the magnitude and direction of the hiker's total displacement? a.3.5 km, 22 south of west b.6.4 km, 45 north of west b.3.5 km, 22 north of west d.6.4 km, 22 south of west 6. Identify the following quantities as scalar or vector: the velocity of a snail, the time it takes to run a mile, and the free-fall acceleration. a. vector, scalar, scalar b. vector, scalar, vector c.scalar, scalar, vector d.scalar, vector, vectorName 3. A hiker walks due west for a distance of 30.5 km from her base camp. On the second day. she walks 41.0 km South of East @ 45 degrees until she disco she discovers the cave she wanted to see. Determine the magnitude and direction of her resultant displacement between the base camp and the cave.
