The particle changes direction when the velocity changes sign, so you would have to find out what specific times t, the function's velocity goes from neg->pos or pos->neg.

- anonymous

You can set the v=0

Does this make sense?

I already did it. But I was thinking about what to do with -2.
I came up with 3(t-2)(t+2)=0
t=2, what shall I do with -2? There's no negative time -.-

- anonymous

Yup, if you can't have -2 but 2 is also an answer, the answer will be.....?

- anonymous

2?

- anonymous

Yup. I haven't done the problem, but if that was your point of confusion, yes, if you have something for t that doesn't make sense (such as when t=0, or neg.) you can disregard it and only use the positive answer.

So that's it. I can do it now. Thanks
