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(t2),sin(t2),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(t2),2tcos(t2),0) speed: 2t. After wards, I got stuck. Any advice would be appreciated.
