Sorry, I'm new to the forum so I didn't realize those option were there. I've edited my original post so hopefully it's easier to read. You are also correct, I meant the magnitude of the vector. I also edited it to make that more clear. These edits probably don't matter too much as I think I...

Sorry bout that, here’s my work: va= 3 m/s i-hat + 2 m/s j-hat = 13^1\2 m/s vb= 3 m/s I-hat + 4 m/s j-hat = 25^1/2 m/s -12 J = Kf - (1/2*2((25^1\2)^2 + (13^1/2)*2) -12 = v1f + v2f - 38 J 26 J - v2f = v1f 2 kg (3 m/s i-hat + 2 m/s j-hat) + 2 kg (3 m/s I-hat + 4 m/s j-hat) = 2 kg (v1f + v2f) 2 kg...

Homework Statement In my reference frame, I see two carts collide. Both cart A and Cart B have a mass of 2 kg. Cart A has initial velocity v= 3 m/s i-hat + 2 m/s j-hat, cart B has initial velocity v= 3 m/s I-hat + 4 m/s j-hat. 12 J are released in the collision. In previous parts of this...
