initial position = 25 cm, initial velocity = 3.15 cm/s, initial acceleration = -0.065 cm/s²

initial position = 31 cm, initial velocity = 2.75 cm/s, initial acceleration = -0.155 cm/s²

initial position = 25 cm, initial velocity = 4.55 cm/s, initial acceleration = -0.235 cm/s²

initial position = 40 cm, initial velocity = 5.20 cm/s, initial acceleration = -0.335 cm/s²

A train is traveling to the right along its straight railway track. The equation for the position of the train as a function of time is given by x(t) = 25.0 cm + (3.15 cm/s)t − (0.0324 cm/s2)t2. What are the initial position, initial velocity, and initial acceleration of the train?
