Carrying groceries

  1. Nov 29, 2014 #1
    1. The problem statement, all variables and given/known data
    1. You carry a 7.0-kg bag of groceries 1.2 m above the level floor at a constant velocity of 75 cm/s across a room that is 2.3 m wide. How much work do you do on the bag in the process?

    2. Relevant equations
    KE=(1/2)(m)(v^2)

    3. The attempt at a solution
    I haven't a clue where to start. Any help would be appreciated and thanks!

    What force do you apply to the bag for the 2.3m? What direction is that force in? How do you calculate work done based on a force and a distance (preferably as a vector equation)?

    Start off by writing in words the definition of Work Done that you will need here.
