What i have now is the initial relative position of A from B, which is 5j
initial velocity of A is 40i + 30j, the direction is changed so that it can overtake B.
Velocity of B is 12i + 16j.
I can find the speed of A, which is 50.
I tried to let the new velocity of A be 50(ai + bj), then here's the problem:
I tried to use
[tex] \\vec{r}_A = \\vec{r}_B [/tex]
r_A=r_B for which r represents the displacement.
but there are 3 unknowns and I'm stuck there...
*I'm having problem with the latex code... hope u can understand
