Consider the trajectory r(t) =   t2+1t2-vt+1. Find a vector n per pendicular to the curve describe by this trajectory at time t = v.

Hint: Sketch a schematic figure showing axes, the origin, the curve described by this trajectory, by the position vector r(t) at time t=v, and the vector n to be found.

Answer: n = <___,___>
