A plane is flying 100 km/h to the north. The wind begins blowing 20.0 km/h to the south. What is your resultant displacement?

Question

Magnitude: (The answer should be a whole number. Do not include units.) 80Direction (abbreviate direction):

Answer 1

Please note that you are giving a velocity but asking for a displacement. Are you sure you aren't being asked for the resultant velocity?

Your velocity becomes 80 km/hr north. Your displacement would be "80t" km north where "t" is the number of hours traveled.
