7.
I hope you noticed that if the object moves to the left the displacement in negative and if the object moves to the right the displacement is positive, is this true?
A.
True
B.
False
Correct Answer A. True

When adding two or more vectors together you simple add the x values together then the y values together, but never x values to y values. So if an object goes from E to D then to A the solution is 0x + 6y for E to D then 15x + 0y added together its (0x + 15x) + (6y + 0y) so the total displacement is 15x + 6y. What is the displacement of an object that moves from E to D then to A?
Correct Answer 15x + 6y 15x+6y 15x +6y
9.
What is the displacement of an object that moves from E to D then to C and finally to B (or E to B)?
Correct Answer 15x + 15y 15x+15y
10.
What is the displacement of an object that moves from D to C to B then to A and finally D?
Correct Answer 0x+0y 0x + 0y 0
