Question
Consider the following lines.
r(t) = (3t+1, 3t+2, 6t − 1), for − ∞ <t<∞
R(s) = (s+ 4,2s +5, -4s+5), for -∞<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.
a. Select the correct choice below and, if necessary, fill in the answer box to complete your answer.
OA. The lines intersect at
.
(Simplify your answer. Type an ordered triple.)
OB. The lines do not intersect.
b. Choose the correct answer below.
A. rand R describe the paths of two particles and the particles do not collide.
OB. rand R describe the paths of two particles and the particles collide.
OC. rand R do not describe the paths of two particles and the particles do not collide.
D. r and R do not describe the paths of two particles and the particles collide.
