Homework Statement
A particle moves along the parabola [tex]y = 4x^{2} [/tex] such that it's x coordinate increases at a steady rate of 5 units/minute.
How fast is the particle's distance from the origin changing when it is at the point (1,4)?
Homework Equations
The Attempt at a Solution
I honestly have no idea how to start this problem. A couple of ideas that pop up in my head are to take the derivatives [tex]\frac {dx}{dt}[/tex] and [tex]\frac {dy}{dt}[/tex] and use them to take the derivative of the distance formula from the origin, but there is no t...
I have no idea. Someone help get me started?
