    Why Isn't the String's Mass Included in Block B's Tension?

    Homework Statement In the diagram above, a massless string connects two blocks- of masses m1(left) and m2(right), respectively- on a flat frictionless tabletop. A force F pulls on Block A, as shown. If the string connecting the blocks were not massless, but instead had a mass of m, figure...

    Relationship between normal force and sum of the force in elevator problem

    Homework Statement A 80.8 kg man inside a 40.0 kg dumb-waiter pulls down on the rope. At that moment the scale on which he is standing reads 200N. Determine the elevator's acceleration (basically the man is inside the elevator pulling a rope that goes around the pulley, which makes the...
