If the question doesn't specify any directions, and the final answer is just a magnitude...(or should you indicate 'in the positive direction' anyway?), do you still put a line over the v?
I also notice in books, the initial and final velocities don't have the line/arrows over the top to show it's a vector, it's not bolded either.
If you use change in speed over change in time to find acceleration (question uses speed but is implied that it's heading in one direction only), is acceleration then a scalar?
