7. At an intersection car B was traveling south and car A was traveling 30° north of east when they slammed into each other. Upon investigation it was found that after the crash the two cars got stuck and skidded off at an angle of 10° north of east. Each driver claimed that he was going at the speed limit of 50 km/h and that he tried to slow down but couldn't avoid the crash because the other driver was going a lot faster. Knowing that the masses of cars A andB were 1500 kg and 1200 kg, respectively, determine (a) which car was going faster? 10° }30° (b) the speed of the faster of the two cars if the slower car was traveling at the speed limit.
