The acceleration a(t) of a particle is -4a^2xi -a^2yj. The particle is initially at rest at the point (a, b). 1) show that the particle oscillates along the arc of the parabola 2ay^2 = b^2(x+a). 2) Find the velocity of the particle whenever it is at the points (a, -b) and (-a, 0).​

Can anyone me with 32,33,36,37,and 40.
