20) Which of the following graphs represents the maximum height reached by a projectile versus its initial y-direction velocity?
I have attached the image for this question.![2013-03-31 18.57.47.jpg 2013-03-31 18.57.47.jpg](https://forums.studentdoctor.net/data/attachments/14/14856-1f0c54c2fab344bc51f79755b2d05676.jpg)
I understand why it isn't Choice A and D. The correct answer is choice C. I thought it was B because as height increases velocity decreases and approaches zero. Parabola at peak is where velocity is zero so how is it choice C? Please explain.
Also - I know that Height is proportionally related to Vinitial Square so it is a parabola but which way should it be pointing. Thank you, really appreciate the help.
