Two cars collide at an intersection. Car A, with a mass of 2000kg , is going from west to east, while car B, of mass 1500kg , is going from north to south at 13.0m/s . As a result of this collision, the two cars become enmeshed and move as one afterwards. In your role as an expert witness, you inspect the scene and determine that, after the collision, the enmeshed cars moved at an angle of 60.0? south of east from the point of impact.
How fast was car A going just before the collision?
