    Blocks
In summary, two blocks with masses of 2 kg and 3 kg are pulled by a force of 25 N on a floor with a coefficient of friction of 0.3. The acceleration of the blocks is calculated to be 2.06 m/s^2 in the same direction as the force.

Blocks on Floor - I got it!

Homework Statement


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?

Homework Equations



F=m*a

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.
