A truck of mass 2630 kg and a car of mass 890 kg in a demolition derby are about to crash into one another. The truck is moving with a speed of 10.2 m/s at an angle of ý = 50.4° and the car is moving with a speed of 11.5 m/s at an angle of 0 = 34.6° as indicated in the figure. The collision is perfectly inelastic. What is the y component of the velocity of the wreck just after the collision?
