    1. The problem statement, all variables and given/known data
    Shopping part moves 40.0m/s, makes a 90degree turn and moves 15.0m. Another 90degree turn and moves 20m. What is the total displacement?

    Here, I need more help with which equation to use. Please give me that, and I will try it on my own. Thank you


    2. Relevant equations



    3. The attempt at a solution

    Welcome to PF.

    There is no equation really.

    Just draw a diagram and figure the total displacement given the 3 displacements that go into it.

    You can do it algebraically by adding x direction components and y direction components and then using the Pythagorean to determine the result. (Signs matter.)
