Position vector ra ship A is : (initial position) + (displacement)
When both ship collide, they will have same position at the same time : ra = rb
Position vector of C relative to D is : rc - rd
Distance between two vessels is : I rc - rd I
v=u+at
s=ut+1/2at^2
v^2=u^2+2as
s=1/2(u+v)t
Gradient of the speed-time graph = acceleration of the particle
Area under the graph = distance travelled by the particles
A system of forces acting on a particle is said to be in equilibrium if their resultant is the zero factor.
*plz don spread rumours tat i did not study for my trials this time... i may go out for a movie n some other events but its one form of detressing mah... haha

Pat, I trust you that you have prepared for this trial exams well enough. I have eyes and I can be a proof, in case you need. I trust that there will be a great difference in your results because God'll provide!!! Happy Holidays!!!
