Unit tangent vector, unit normal and tangential and normal componets of acceleration

Attachment 25322

There is a part b) which asks to find the tangential and normal components of the acceleration vector. It would be appreciated if both parts could be answered.

What do you expect?
Do you think that we are here to do your work for you?
There are sites that do that for a price.
We only help. So post some of your work so we can help.

off dude. I am asking for help, if I knew what I was doing I wouldn't be here, right?

Hi theone1145,

Do you have equations somewhere for T and N in terms of r? If so, what happens when you plug in this r(t) function?

Thanks,
