QUESTION 2 An object moves along the s-axis, where its position relative to the origin is given by the function s(t) = at3 - 20t² + ct+d, where s is in centimetres and it is in seconds. Other information about the motion of the object is given below. the object changes direction at 4 seconds Vertex • the total distance travelled in the first 5 seconds is 342 cm • acceleration of the object at 7 seconds is 36 cm/s² (+) • the second time the object changes direction, it is located at s = 344 cm. Determine the exact values of a, c and d.
