2. Two cars, both with mass m, collide and stick together. Prior to the collision, one car had been travelling north at a speed of 2v, while the second was travelling at a speed v at an angle p as shown on the diagram. After the collision, the two cars travel with a Vinal at an angle 0 NORTH EAST, again, as shown in the figure. Determine the final velocity if v = 25 m/s and p = 30•. Vinal 2v E
