A particle initially at the origin travels in uniform motion with velocity v=2i-j-2k. Find position venctor vector r(t) of a particle at time t. Find equatio for the plane passing through the origin and perp. to the tragectory of the particle. And find when and where the particle reaches the origin-centered unit circle.
