Finding the Curvature of the path of a particle

Question

How do I find the curvature of the vector when t=5?

The function is:

    v[t_] := {2 t^4 + 2, 6 t^3 + 1, 3 t^2 + 4}

Answer 1

v[t_] := {2 t^4 + 2, 6 t^3 + 1, 3 t^2 + 4}

curv = ArcCurvature[v[t], t]

You sent t to 5 like so:

N[curv /. t -> 5]

There's another way but I am letting this up to @cvgmt to show it
