# Problem:  shows the position-versus-time graph for a moving object.(A) At which lettered point or points is the object moving the fastest?(B) At which lettered point or points is the object speeding up?(C) At which lettered point or points is the object moving to the left, if the positive x-direction corresponds to its rightward movement?(D) At which lettered point or points is the object turning around?

###### FREE Expert Solution

In the figure, we are given a position-time graph. We'll recall concepts associated with velocity-time graphs and answer the questions.

(A) The object moves fastest at the point on the curve where the slope is the greatest.
