113 N in the direction kicked by Red #3.
13 N in the direction kicked by Blue # 5.
113 N in the direction kicked by Blue # 5.
An airplane heads due north at 100 m/s through a 30 m/s cross wind blowing from the east to the west. Determine the resultant velocity of the airplane (relative to due north).
104.4 m/s at 29 degrees west of north.
104.4 m/s at 29 degrees east of north.
104.4 m/s at 29 degrees north of east.

A mountain climbing expedition establishes a base camp and two intermediate camps, A and B. Camp A is 11,200 m east of and 3,200 m above base camp. Camp B is 8,400 m east of and 1,700 m higher than Camp A.
Determine the displacement between base camp and Camp B.
A
B 20,203 m

Two vectors are considered to be equal if they have same magnitude and ..............
A different direction
B positive direction
C same direction
D negative direction
When we add the following vectors and determine the resultant. V1 = 3.0 m/s, bearing 45 deg, and V2 = 5.0 m/s, bearing 135 deg we get:
5.83 m/s, 76 deg.
8.0 m/s, 76 deg.
5.83 m/s, 104 deg.
8.0 m/s, 104 deg.
Add the following vectors and determine the resultant. 5.0 m/s, 45 deg and 2.0 m/s, 180 deg
The resultant is:
3.35 m/s, 66.5 deg
3.85 m/s, 66.5 deg
3.85 m/s, 32.5 deg
3.35 m/s 38.5 deg.
