The particle then changes direction and travels 11, 1 cm at an angle of 38.80 above the positive -axis. What is the particle's displacement vector after these two motions? O 17.7 cm. 6.710 below the positive a-axis O 21.8 cm. 5.030 above the positive -axis O 21.8 cm. 5.03' below the positive c-axis 17.7 cm. 6.710 above the positive a-axis Question 10 O pts Cory is looking for a good campsite.
