Final answer:
True. A position vs time graph of an object that is speeding up is represented by a straight line with a positive slope.
Step-by-step explanation:
True. A position vs time graph of an object that is speeding up is represented by a straight line with a positive slope.
For example, if a car starts from rest and gradually increases its speed over time, the position vs time graph will be a straight line that starts at the origin and has a positive slope.
Therefore, the correct answer is a) True.
