Intersecting lines and colliding particles Consider the lines r = 〈 2 + 2 t , 8 + t , 10 + 3 t 〉 and R = 〈 6 + s , 10 − 2 s , 16 − s 〉 a. Determine whether the lines intersect (have a common point), and if so, find the coordinates of that point. b. If r and R describe the paths of two particles, do the particles collide? Assume t ≥ 0 and s ≥ 0 measure time in seconds, and that motion starts at s = t = 0.
