Question

20. The moose's resultant displacement is directed ?

Algha A very large moose is abserved wanderinge through western Massachusetts First, the moose travels through a displacement D 5.00 miles, directed 30 Then the moose undergoes a displacement West of South 4.00 miles, directed 80 South of East Thus, the moose undergoes a resultent displacement R= D+D 21 In the following, assume that the +y direction is defined as due North and that the +x direction is defined as due East, as shown in the figure. 16. True or False: R=D+ |D ? a. True 6. False 17. True or False: Dy and D.. are both negative? a. True b. False 5 COS 30 has y component-vector equal to 18. Displacement D d. 2.50 miles i c. 2.50 miles. e. 4.33 miles a. 2.50 miles7. b. 4.33 miles. R has a magnitude of 19. The moose's resultaqt displacement a. 10.1 miles. d. 6.40 miles c. 1.00 miles. 6. 8.46 miles. e. 9.00 miles. Ad (De Use SOFF CaH TOA 20. The moose's resultant-displacement is directed c. 77.7° Sef W. b. 77.7 W of S a. due South-West. e. 4.58° W of S 4.58 S pf W d. SA
