An object moves in one dimension along the x-axis. At time t = 0, the object is located at position x = 1 m and has a velocity v = 1 m/s. The object's acceleration varies as a = 3t, where a is in m/s and t is time in seconds. A student incorrectly derives the equation for the object's position as x = t3 + 1, where x is in meters. Which of the following describes a possible error that could have resulted in the incorrect equation? The student's equation does not account for the initial position of the object. (B The student's equation does not account for the initial velocity of the object. @ The student's equation does not substitute a = 3t in the fat? term. D The student's equation should not have a +1 term, as integrating the acceleration function twice yields x = 4+3
