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?
