Homework Statement



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

Homework Equations



1st and 2nd derivatives??

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?
