If two objects travel through space along two different curves, it is often important to know whether they will collide. The curves might intersect showing that objects will be in the same location at some time, but we need to know whether the objects are in the same location at the same time Suppose the trajectories of two objects are given by r1(t)=(t, t, t3+7(t-1)) and r2(s) = (1+3s, 1+9s, 1+428) Find two points where the trajectories intersect. Enter the point with the smaller 2-value first. Point = ( Point = |) att = and s = ) att = and s = ? 1. Do the objects ever collide?
