Force problem

  1. Feb 26, 2005 #1
    A horizontal rope is tied to a 56.0kg box on frictionless ice. What is the tension in the rope if the box moves at a steady 4.80 m/s? So far i found that the only forces acting on the box are normal force, tension, and weight.
    The x components are: T_x_=T, n_x_=0, and w_x_=0. the y-components of the forces are : T_y_=0, n_y_=n, and w_y_=9.8(56) (w=mg)
    should i use the motion equations to maybe solve for the displacement of x? i tried doing that but i dont get the right answer...im stumped!!

    is this the entire question?
    is there a given answer?
    well if the velocity is steady, then there is no acceleration
