Can someone help me with relative motion

  • #1

Homework Statement


if a car 1 is traveling north at 13m/s
and another car (2) is driving 20 degrees north of west at 7.0m/s

1.What is the velocity of car 1 relative to car 2
2.What is the velocity of car 2 relative to car 1?

i don't understand how to solve this? could someone help, are the relative velocities different?


Homework Equations





The Attempt at a Solution



My attempt...

components of car 2
sin 20 = op/hyp = op/7
y=2.39 North

cos20=x/7
x=6.58 West

then i dont know what to do

Of course we can help you solve the question, but we won't do it for you. You need to show some effort in solving the question yourself before we can help you.
