suppose that the position vector fot a particle is given as a function of time by r(t) =x(t)i + y(t)j, with x(t) = at+b and y(t) = ct^2 + d, where a= 1.50m/s, b =1.25m, c= 0.123m/s^2, and d =1.02ma. calculate the average velocity (v in m/s) during the time interval from t= 2.20s to t = 3.90sb. Determine the velocity at t = 2.20s in m/sc. Determine the speed at t = 2.20s in m/s
