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!
