Acceleration Graph for an Object with Given Force-Time Graph

[kdb004]

Homework Statement

A force with x-component F_x acts on a 2 kg object as it moves along the x-axis. A graph of F_x versus t is shown in the figure. Draw an acceleration graph (a_x versus t) for this object.

F = ma

You have F (in the graph) and you have m. What do you need to do to get a?

im not sure, i have a horrible teacher who expects us students to figure this stuff out ourselves so i don't know how a force vs. time graph compares to an acceleration vs. time graph

Re-read the question I posed above and you should be able to come to the answer. Saying "I don't know because my teacher is awful" is not an acceptable answer to the question I asked you, because it's just simple algebra.

well no offense but this guy is a horrible teacher, he made his own book for the class too and its definitely lacking the goods needed to help us figure some of this stuff out. Thanks for the help though, I've been at this stuff all day so my mind is about fried lol, but after i re read what you said i came up with the correct graph for the problem. again, thanks for the help

Well, in the future it would be good to at least say something like, "I know F = ma , but am unsure how it is applied to this problem" ... or something that demonstrates you aren't just looking for a handout.

No problem.

ya, handouts are nice but i actually want to know how to work this stuff out too. i guess i forgot to say that in any of my posts
