A particle moves along the curve [itex]y(x)=x^2-4[/itex] with constant speed of 5 m/s. Determine the point on the curve where the max magnitude of acceleration occurs and compute its value.
Homework Equationsradius of curvature
The Attempt at a Solution
I have assumed that 'constant speed' means [tex]v_t=5 \Rightarrow a_t=0[/tex]
So now I have to find where a_n is maximum. Any hints to get me going here?
