In a military test, a 575 unmanned spy plane is traveling north at an altitude of 2700 and a speed of 450 . It is intercepted by a 1280 rocket traveling east at 725 .

If the rocket and the spy plane become enmeshed in a tangled mess, where, relative to the point of impact, do they hit the ground? Give the direction as an angle east of north.

2. Relevant equations

F = ma

p = sqrt((m_1v_1)^2+(m_2v_2)^2)

vinitial = p/sum of m

sf = si + vi*t +1/2a*t^2

3. The attempt at a solution

I found Vinital by doing v = p/m, and got 519.352 m/s.

then i plugged that value into yf = yi + vi*t + 1/2a*t^2, and using yf = -2700.

then i used the quadratic formula to solve for t, and using the negative root (because of logistics) and ended up with t = 4.966 seconds.

then plugged that into xf = xi + vi*t, and ended up with 2.58 km.

the answer should be 12.2 km. so, i'm not sure what I am doing incorrectly.
