    1. The problem statement, all variables and given/known data
    ive reduced a problem down to one last part, and where i need the normal and tangential acceleration components of a moving particle. we are given the following: $$a=xi+yj$$ and $$v=ui+zj$$ where a and v are acceleration and velocity and the x,y,u,z are the components.

    note we are only in 2 dimensions

    i cant think of any way to proceed. thanks for any help!

    So when you say you want the tangential acceleration then that would be the a component in the direction of v

    So look at the dot product of a with v

    In a similar vein you should now know how to get the normal component.

    If you have the equation for the velocity vector v, then you should be able to write down an equation for a unit vector in the direction of the velocity vector. What is that equation?
