Normal force, acceleration and tension

  1. Nov 2, 2008 #1
    1. The problem statement, all variables and given/known data

    How do you find the normal force and acceleration of a 72 N block that is pulled across the floor with tension force of 33 degrees. As is slides the coefficient of kinetic friction between object and the floor is 0.32.


    2. Relevant equations



    3. The attempt at a solution

    Welcome to PF.

    Generally the normal force is going to be m*g.

    The Tension is apparently upwards which means that the upward component the tension T*Sinθ is pulling up and reducing the m*g

    Whatever your normal force times the coefficient of friction is it will retard the forward pull of the Tension, which is the horizontal component of T.
