Motion in 3d - acceleration and its components

Hi
 
I have found the vector for the acceleration of a particle in 3d, however I have been asked now to give its component that is tangential to the trajectory of the particle. Can I get some help with this please? Thanks

Thanks. Just to be clear, at the end you are saying that I should be using scalar multiplication, and not vector multiplication, yes?

Yes, since you want the projection of a in the direction of the unit vector T.
