Car A is speeding in the positive x direction and is about to run through a red light and collide with car B ( heading in the positive y direction). At the time of collision va=vai m/s and vb=vbj m/s. Ma=1500 kg, Mb=2700 kg. They move together as a single body after collision and slide at an angle of 31 degrees for 9.4 m. The coefficient of friction between the cars and road is 0.85. Determine the speed of each car at the time of collision.
