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.
