    Well, what does it mean if the vector ai+bj is parallel to ci+dj?

    Set your velocity vector to equal 2{\bf i}+{\bf j} at time t=T and solve for T

    I've done that, the solutions are weird or wrong.

    ( 4+4T) i+ (6T) j = (2i+j)

    But if I equate the i and j components, I obtain random values for T??

    Sorry I forgot the scalar.

    Make it equal to (2k) {\bf i} + (k){\bf j} and solve.

    Thank you, the numbers worked out splendidly

    Do you understand why you need to include the k?

    Yes, earlier, I added the scalar part to the (4+4T) i + (6T) j part;however, that is wrong because that wouldn't equate the two parts.

    Thank you.
