**v**is the instantaneous tangential velocity of the particle. Since the tangential deceleration and normal acceleration are equal, this means that the particle is decelerating tangentially at a rate

^{2}/R, v**v**

^{2}/R.**In other words,**

To find the velocity v as a function of distance covered s we could use the relation between v and t to find the relation between s and t and so on... however, a simpler trick exists,

(b) Once (a) is done, we already know that the tangential and normal acceleration components are equal, thus, the net acceleration must be,

knowing the relation between v and s we can determine the total acceleration as a function of s as,
