An object is slowing down while traveling clock-wise around a circle of constant radius. Which of the following statements are true regarding this situation?
a. The object's acceleration vector points directly towards the center of the circle.
b. The object's acceleration vector has a component that points towards the center of the circle.
c. The object's acceleration vector has a component that points radially outward.
d. The object's acceleration vector has a component that points tangent to the circle and in the direction of its motion.
e. The object's acceleration vector has a component that points tangent to the circle and in the opposite direction of its motion.
