Homework Help: Particle Uniform circular motion problem

  1. Jun 22, 2015 #1
    1. The problem statement, all variables and given/known data
    A particle moves along a circular path over a horizontal xy coordinate system, at constant speed. At time t1 = 3.30 s, it is at point (5.10 m, 6.80 m) with velocity (3.90 m/s) ## \hat j ##and acceleration in the positive x direction. At time t2 = 9.90 s, it has velocity (–3.90 m/s) ## \hat i ##and acceleration in the positive y direction. What are the (a) x and (b) y coordinates of the center of the circular path? Assume at both times that the particle is on the same orbit.

    2. Relevant equations

    3. The attempt at a solution
    im having trouble getting started on this one. if only drawn a diagram with the particles plotted along the orbit and their tangential velocity vectors
    the point at t=3.30s is on the very left of the orbit and the point at t=9.90s is on the very bottom of the orbit.
    the center point of the circle is in quadrant 1

    added a link to my sketch, not sure how to insert that as an image on here.

    View the image. Then copy that image you're viewing. Then paste it here.

    It is quite difficult to read.
