Which vector below goes form (0, 0) to (2, 2)? a. a b. c c. d d. b

D. b

Explanation:

We see that all vectors start from the origin (0,0). We need to find the vector that goes to (2,2). We can notice that the point (2,2) is located in the 1st quadrant: in fact, the x-coordinate of the point is 2, and the y-coordinate is 2 as well. Therefore, the only vector that goes into the 1st quadrant is b, so this is correct choice.

The other vectors goes to:

a: from (0,0) to (-4,2)

c: from (0,0) to (-2,4)

d: from (0,0) to (2,-4)

4

4

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.
