(a) Consider an object's motion, and suppose its position function is given by r(t)= (4t²-2t)i^ +(3t²+1)j^,where t is time in seconds. (b) What is the average velocity between 0 s and 1.0 s (in m/s)? Express your answer in vector form. Choose the correct option from the following: A) (2,4)m/s
B) (7,7)m/s
C) (8,5)m/s
D) (−1,2)m/s
E) (5,4)m/s
