    like when it says what the length of\ the x- component does it mean like 8 because its 8

    1. Length of x component is x2-x1. Did you solve that already? I see your work at the bottom of the graph.

    This is more like pre algebra. If you are taking physics you should know this. x2-x1=9-1=8

    That would be your displacement vector. Displacement is (endpoint-starting point)

    It is a right triangle and you are trying to find displacement vector. You got the x and y components. You do know they tell you hints in the worksheet right? Have you passed Algebra yet?

    square root of 100 is 10

    yes. that is displacement. Displacement is like the distance between your ending point and starting point.

    For 4. what is distance traveled and what is your displacement? Then you would compare them. Pretty common sense in this question.

    14 is the distance

    Total distance=amount of distance the truck traveled (includes every distance)
