(a) If he coasts around one half of the circle, find the magnitude of the displacement vector.  = _____m   (b) Find how far the person skated. = _____m   (c) What is the magnitude of the displacement if he skates all the way around the circle?  = _____m

what are the magnitude and angle of a vector with these components?  Bx= 7.8 m and By= 10.2 m

Vector A= -6i+4j Vector B= -3i-8j How do you find the quantity of abs(A+B)?

Vector A has a magnitude of 26 units and points in the positive y-direction. When vector B is added to A, the resultant vector A + B points in the negative y-direction with a magnitude of 11 units. Find the magnitude and direction of B. magnitude unit(s) direction ---Select---

Vector R has a magnitude of 10 m. Its z component is 8 m. What are the possible values for its y component? Express your answer in meters. If there is more than one answer, separate them by a comma.

Can someone please help me understand this question and how to get the answer? Two displacement vectors have magnitudes of 5.0 m and 7.0 m, respectively. If these two vectors are added together, the magnitude of the sum is: 1.) equal to 8.6m 2.) could be as small as 2.0m or as large as 12.0m 3.)is equal to 2m 4. or is equal to 12m. Thank you. I am really confused.

Margaret walks into the store using the following path: 0.870 mi west, 0.330 mi north, 0.140 mi east. Assume north be along the positive y axis and west be along the negative x axis. What is the magnitude of her total displacement? In what direction is the displacement vector? Enter the answer as an angle north of west.
