Homework Help: Free body diagram of a car

  1. Sep 25, 2010 #1
    1. The problem statement, all variables and given/known data
    A car pushes a block across the floor. (assume that it is moving from left to the right)

    Draw a free body diagram for the car showing: Force by block on car. Force of friction. Force of Gravity. Normal force.

    2. Relevant equations



    3. The attempt at a solution

    Normal force Straight up, gravity straight down. Force of box on car going left + force of friction going left.

    alright, i'll attach something for you

    Note: Remember that no matter what your object is, it will remain as a box. Do not bother into details, only what that object (or system) it is.

    is "force by rabbit" the same as force of car on rabbit? I interpreted that as the equal and opposite reaction push back onto the car from the rabbit.

    they are action-reaction pairs I think, but no, they are seperate forces. Remember to label each one with a different name.

    when did the block change into a rabbit?
    if the friction force on car and force of block on car both point left, how does the car move to the right?
