Does an acceleration in the positive direction always mean that a moving object is speeding up?

The three graphs represent the position-time graph for the objects moving along the X-axis.

1) Which graphs represent an object moving in a positive direction?

2) Which graph is physically not possible?

 

An object that moves along a straight line has the velocity-versus-time graph shown in the figure below. At time t = 0, the object has position x = 0.

a. At time t = 5 s, is the acceleration of the object positive, negative, or zero?

b. At time t = 8 s, is the object speeding up, slowing down, or moving with constant speed?

c. Write an expression for the position of the object as a function of time. 

d. Use your expression from part (c) to determine (if any) at which the object reaches its maximum position.
