(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A particle is constrained to move around the unit circle in the xy plane according to the

formula (x,y,z)=(cos(t^{2}),sin(t^{2}),0), t[tex]\geq[/tex]0.

At what point on the circle should the particle be released to hit a target at (2,0,0)?

2. Relevant equations

None

3. The attempt at a solution

I computed the velocity vector and speed of the particle as functions of t:

velocity: (-2tsin(t^{2}),2tcos(t^{2}),0)

speed: 2t.

After wards, I got stuck. Any advice would be appreciated.
