The position of an object moving in a straight line is given by x = At + Bt 2 + Ct 3 , where A = 3.0 m/s, B = -4.0 m/s 2 , and C = 1.0 m/s 3 (a) What is the position of the object at t = 0, 1, 2, 3, and 4 s? (b) What is the object's displacement between t = 0 and t = 2 s? Between t = 0 and t = 4 s? (c) What is the average velocity for the time interval from t = 2 to t = 4 s? From t = 0 to t = 3 s?

Therefore the position of the object at t = 1 s is 0 m.
