Curvilinear motion

  1. Jan 28, 2011 #1
    1. The problem statement, all variables and given/known data

    A particle travels along the path y^2 = 4x with a constant speed of v = 4 m/s.
    Determine the x and y components of the particle's velocity and acceleration when the particle is at 4m

    2. Relevant equations

    1st and 2nd derivatives??

    3. The attempt at a solution

    not sure what to do..

    Remember that the velocity vector is tangent to the curve at all points. So, you should find at what x-value is the particle at 4m (do you remember the integral definition of distance for a curve?), then find the derivative at that point...

    Do you see where to go after that, given the magnitude of the velocity vector?
