Question

3. After takeoff, an air-traffic controller locates a small plane 12.0 km southeast of the airport. At this point, the plane turns 20.0 to the east of its original flight path and flies 21.0 km. What is the magnitude of the plane's displacement from the airport? gymnast tumbles forward 4.0 m, does cartwheels to the left for 6.0 m, and climbs a vertical rope to a height of 3.0 m. What is the magnitude of the gymnast's displacement? Graphically determine the difference in displacement, Ad, for each pair of displacements below. 5. a. di 2.0 m, d2 3.0 m b. d2.0 m, d2+ 2.0 m c. d1 = + 2.0 m, d,--2.0 m d, d1 = 2.0 m at 35° north of east d 3.0 m at 25° south of east

Explanation / Answer

3)

To solve this problem, use Law of Cosines because you only need displacement

Ans: 32.3 km
