Two vehicles collide and stick together. After the collision, their combined ymomentum is 2.40 x 10^4 kilogram meters/second, and their xmomentum is 7.00 x 10^4 kilogram meters/second. What is the angle of the motion of the two vehicles, with respect to the xaxis?
Could someone please assist?
EDIT:
Okay, so I tried myself and here's what I did:
2.40 x 10^4 * 7.00 x 10^4 = 168 = 16.8 degrees
Not sure if right, anyone want to confirm?

Best ResponseYou've already chosen the best response.0I'm not sure what you're doing, but momentum is \[\vec p = m \vec v\] you should make a drawing for initial case and final case, are you given directions?

Best ResponseYou've already chosen the best response.0Anyways to find the angle of the motion we use \[\tan \theta = \left( \frac{ P_y f }{ P_x f } \right)\]

Best ResponseYou've already chosen the best response.0I wasn't given any specific directions, all I wrote was all that was there... Ah, alright, so it'll be tan(theta) = (2.40 x 10^4 (f) / 7.00 x 10^4 (f))?

Best ResponseYou've already chosen the best response.0The f here just means final case, but yes, that's fine \[\tan \theta = \left( \frac{ 2.4 }{ 7 } \right)\]

Best ResponseYou've already chosen the best response.0By the way the reason I used 2.4 and 7 and did not include 10^4 because 10^4/10^4 is just 1.

Best ResponseYou've already chosen the best response.0Right, we take the inverse! :)

Best ResponseYou've already chosen the best response.0Oh wait...would it look something like this? (theta) = tan^1= (2.4/7)

Best ResponseYou've already chosen the best response.0What did you get for the angle?

Best ResponseYou've already chosen the best response.0Do I divide the 2.4 and 7 before doing so? Because I did, getting 0.34 and the final angle: 18.8 degrees

Best ResponseYou've already chosen the best response.0That's fine, but don't round numbers until the final answer, you should get 18.92...degrees

Best ResponseYou've already chosen the best response.0Ah, okay! And here one of the answers is 18.9 degrees, guess we got it. :) Thanks once again! ^ ^
