Question:

Determine whether the following statements are true and give an explanation or counterexample.

b. If the acceleration of an object moving along a line is always 0, then its velocity is constant.

c. It is impossible for the instantaneous velocity at all times a ≤ t ≤ b to equal the average velocity over the interval a ≤ t ≤ b.

d. A moving object can have negative acceleration and increasing speed.
