Set your velocity vector to equal at time and solve for

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 and solve.

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.
