A particle moves in a plane with trajectory given by the polar equation,

r = a(1 + cos );where a is a positive constant Suppose that the particle moves such that theta(t) =omega for all t; that is, the angular velocity theta is constant.Show that the

acceleration has radial component -aomega^2 (2 cos +1)and transverse component

-2aomega^2sintheta
