Not sure how to do these. Any help would be greatly appreciated.

Two particles travel along the space curves r1{t) = (t, 12, t3) r2{t) = (1 + 2t, 1 + 6t, 1 + l4t). Find the points at which their paths intersect. (If an answer does not exist, enter DNE.) (x, y, z) = ( ) {smaller x-value} (X: V: Z) = ( ) {larger x-value) Find the time(s) when the particles collide. (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE.) t: Need Help?
