A particle moves along the x-axis with velocity dx/dt=f(x)

  1. Aug 30, 2008 #1
    I think I am supposed to use the chain rule in this excercise, but I dont know how to. Please helt me.

    A particle moves along the x-axis with velocity dx/dt=f(x). Show that the particle's acceleration is f(x)*f '(x).

    Re: Acceleration

    Can you start by writing down the chain rule?

    dy/dt= dy/du * du/dt

    Re: Acceleration

    Well next, think of how to apply it. Think of how to differentiate f(x) with respect to time.
