How quickly are you moving relative to the ground?

  1. Oct 9, 2016 #1
    1. The problem statement, all variables and given/known data
    On a long bus ride, you walk from your seat to the back of the bus to use the restroom. The bus is driving at 120 km/h , and you walk at 2.5 m/s from your seat to the restroom.
    How quickly are you moving relative to the ground?
    2. Relevant equations
    vpg=vpb+vbg

    3. The attempt at a solution
    120 km/h= 33.4m/s

    vpg= 33.4+ 2.5= 35.83 m/s

    Be careful about what direction the bus and you are going. Use the appropriate sign for each. You shouldn't add if they are in opposite directions.
