Q3: Write down the equation of motion of a mass m constrained to move along the parabola y = x2. Take the gravity to be pointing along the -y direction. Assume that the parabolic path is frictionless. First write the equation of motion in vector form, then write two equations corresponding to the motion along the r and the y directions.
