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 = 3 t, where a is in m/s2 and t is time in seconds. A student incorrectly derives the equation for the object's position as x = 12 t3+1, where x is in meters. Which of the following describes a possible error that could have resulted in the incorrect equation? (A) 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. (C) The student's equation does not substitute a = 3 t in the 12 at2 term. (D) The student's equation should not have a +1 term, as integrating the acceleration function twice yields x = 12 t3

The acceleration of a particle moving only on a horizontal xy plane is given by a→ = 5ti^ + 6tj^, where a→ is in meters per second-squared and t is in seconds. At t = 0, the position vector r→ = (27.0 m)i^ + (36.0 m)j^ locates the particle, which then has the velocity vector v→ = (7.40 m/s)i^ + (2.20 m/s)j^. At t = 2.80 s, what are (a) its position vector in unit-vector notation and (b) the angle between its direction of travel and the positive direction of the x axis? (a) Number i^ + j^ Units (b) Number Units
