To visit your favorite ice cream shop, you must travel 490 m west on Main Street and then 950 m south on Division Street. (a) Find the total distance you traveled. (b) Write your displacement vector in unit vector notation, taking the x ^ direction to be east and the y ^ direction to be north. (c) Write the displacement vector required to return to your starting point in unit vector notation.

A small plane flies a distance d1 = 32 km in a direction θ1 = 64o north of east and then flies d2 = 23 km in a direction θ2 = 18o north of east. What is the magnitude of the net displacement vector of the plane, in units of km and wh is the direction of the net displacement vector of the plane? Express the direction as an angle measured in degrees north of east.
Borsalino wants to buy some ice cream in the nearest convenience store. He has to walk 5.3 meters, 12 degrees in the north of east direction to
reach the doorstep of the convenience store. He then enters the store and walks straight to cashier, two meters due northwest.
Let A be the displacement vector with a magnitude of 5.3 meters directed 12 degrees in the north of east direction, and let B be the
displacement vector with a magnitude of two meters due northwest. Express vectors A and B in unit vector component form.
B =
%3D
The net displacement is given by the vector sum: R = Á +B.
Ř=
By Pythagorean theorem,the magnitude of the displacement is:
meters.
The direction of the resultant displacement is:
north of east.
