Hello all,

i need help with the following question:

Given a 2d plane which has 4 distinct points, C, D, A, B. Points A and B define an infinite line. At time t=0 a player starts moving at a constant velocity from point C to point D, where he arrives at t=1. Determine, if the player hits the wall. If he does, find the corresponding time and position.

I started this problem by taking an infinite length line AB and from the given data , the distance of CD is V(v=velocity from C to D). But I am unable to understand about how to find the intersection of the two lines. I started by trying to find if C and lie on either side of AB or on AB but could not proceed much with this. Can someone plz help me out with problem.

Thanx a lot ,

Aarav
