Homework Help: Frictionless Problem help please?

  1. Jul 15, 2007 #1
    Question Details:
    a 21 kg block sliding on a 13 kg block. All surfaces are frictionless. Find the magnitude of acceleration of each block and the tension in the string that connects the blocks.
    Find the acceleration m/s2 (acceleration of blocks)?
    and the force N (tension in string) ?

    Have found Efy to be 301.5 and Efx to be -82.01, i set the Efy equal to 0 but i dont know if im suppose to add the Efy to the Efx before I set that information equal to M*a to get the acceleration

    A picture would help. Or more details with the question, it is not complete.
