Homework Help: Blocks on Floor - I got it

  1. Oct 21, 2008 #1
    Blocks on Floor - I got it!!!

    1. The problem statement, all variables and given/known data
    A block of mass m1 = 2 kg and a block of mass m2 = 3 kg are tied together and are pulled from rest across the floor by a force of Fp = 25 N. The coefficient of friction of the blocks with the floor is µ = 0.3. (the blocks are being moved in the same direction, to the right).

    a) What is the acceleration of the two blocks?

    b) What is the tension in the string between the blocks?

    2. Relevant equations


    3. The attempt at a solution

    I have only attempted a so far. I added the mass of the two blocks and divided it by the force to hopefully get acceleration.

    I didn't account for friction. I calculated for a and got 2.06 m/s^2.
