Suppose the position vector for a particle is given as a function of time by r(t) = x(t)î + y(t)ĵ, with x(t) = at + b and y(t) = ct² + d, where a = 1.30 m/s, b = 1.35 m, c = 0.121 m/s2, and d = 1.14 m. (a) Calculate the average velocity during the time interval from t = 2.05 s to t = 4.05 s. (b) Determine the velocity at t = 2.05 s. Determine the speed at t = 2.05 s.
