Forces involving a pulley sysem.

  1. Oct 21, 2007 #1
    A block of mass 1.05127 kg lies on a frictionless table, pulled by another mass 3.94644 kg under the influence of Earth's gravity. The acceleration of gravity is 9.8 m/s^2.

    a) What is the magnitude of the net external force F acting on the two mass system connected by the string? got this to be 38.6751 N and its correct

    b) Magnitude of the acceleration of the two masses? I got it to be 7.73857 and its correct.

    c) Magnitude of the tension of the rope between the two masses?

    Not really sure what c) wants...the magnitude part throws me off.
