The graph below shows a plot of the position of a particle as a function of time. I need help determining whether the statements concerning the motion of the particle are true or false. The graph: http://imgur.com/yNeHoF3 ???? - The instantaneous acceleration at B is zero. True - The instantaneous velocity at F is zero. ???? - The average acceleration over segment AE is less than zero. False - The average velocity over segment FG is zero. That's what I have so far! I'm not even sure if the last one is right. I've looked it up, and I can't find how to find acceleration on a position-time graph, only velocity. Any help would be great!
