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 xvalue 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?
