Problem # p032

Motion of Particle along Curve, Path Coordinates
A particle moves along a parabola with constant velocity v = 3 m/sec starting at point A and proceeding towards point B.
Given are the two lengths : a = 1.8 m ; b = 1.2 m which describe the equation of the parabola :

What is the value of the tangential component of the acceleration when the particle is at

What is the value of the normal component of the acceleration when the particle is at
