16. An object moves along the x axis according to the equation \( x(t) =(3.00t^2 -2.00t +3.00) m\). Determine (a) the average speed between t =2.00 s and t = 3.00 s, (b) the instantaneous speed at t = 2.00 s and at t = 3.00 s, (c) the average acceleration between t =2.00 s and t = 3.00 s, and (d) the instantaneous acceleration at t =2.00 s and t =3.00 s.
