Physics problem with masses and pulley and a ramp

  1. Jan 31, 2012 #1
    1. The problem statement, all variables and given/known data

    2 masses m1=50g and m2=5g are connected as shown (sori walang pci) m1 is free to move along a horizontal frictionless table. Neglecting the mass of the cord connecting the two masses and assuming a frictionless pulley. Determine the accelereation of the system of blocks and tension in the cord

    2. Relevant equations

    F=ma
    W=mg

    3. The attempt at a solution

    Force of the tension
    Acceleration

    I really couldn't get how to get the tension when its coming from a pulley
    please help :D

    Re: physics

    The tension is just the reaction over the rope due to the force exerted by the weight of the masses. The tension over the rope is equal to the force exerted by the weights over the cord. You just need to make a diagram of free body, and analyze which components of the weights are acting over the rope in each case, and then make the sum.

    You didn't put a picture, so I'll draw one as I think the problem is, I'm not sure, but I think this is it.

    The cord and the pulley only acts to redirect and transmit the forces.

    Can you go on from here?
