An 8 kg object moving at 10 m/s in the +x direction collides with a 12 kg object moving at 5 m/s in the +y direction. There is no external

force acting on them. After the collision, the two objects move together with the same velocity. A. Draw a diagram of the situation B. Calculate the velocity vector of the two objects after the collision C. Calculate the final speed of the two objects after the collision
