Any insights would be appreciated!

**Problem:**

A 2000 kg truck is traveling east through an intersection at 2 m/s when it is hit simultaneously from the side and the rear. One car is a 1000 kg compact traveling north at 5 m/s. The other car is a 1500 kg midsize traveling east at 10 m/s. The three vehicles become entangled and slide at one body. What are their speeds and direction just after the collision?

**My Attempt:**

Energy east/x: (1/2)*1500*100 + (1/2)*2000*4 = 79 kJ

Energy north/y: (1/2)*1000*25 = 12.5 kJ

Final speed: [itex]\sqrt{2.2^{2} + 5.92^{2} }[/itex] = 6.32 m/s

@Angle: tan^{-1}(2.2/5.92) = 20.4°

**Solution:**

mv

_{xfinal}= 1500*100 + 2000*4 solve for v in x-dir

mv

_{yfinal}= 1000*5 solve for v in y-dir
