Question

The figure is a motion diagram with the clock reading (in seconds) shown at each position. The positions for t? 16 s are offset for clarity, but the motion actually occurs along a single track. Which graph best represents the object's velocity? A,B,C, or D? Pictures uploaded in my comments section

Answer 1

I know it is not C or D... so I'm stuck because it is along a single track, so being on a single track does that mean it is not actually reversing direction?

Answer 2

It can reverse it's direction because being single track does not mean one direction.

Answer 3

ok, so would you think it is graph B? but I'm not sure what the space or skip means in the bottom of graph B under the axis, or if that is even relevant.

Answer 4

It's B.Initially the velocity is decreasing. Then from 9 to 15 s it becomes zero. On 16th second it reverses direction and become non zero ( that is why a skip is there.) and then it remains constant up to 23 s.

Answer 5

It makes sense to me! Thank you! :)

Answer 6

You are welcome :)
