Two cars collide at an icy intersection and stick together afterward. the first car has a mass of 1200 kg and is approaching at 8.00m/s due south. the second car has a mass of 850 kg and is approaching at 17.0m/s due west. (a) calculate the final velocity (magnitude and direction) of the cars. (b) how much kinetic energy is lost in the collision

![K.E_{initial}=1/2m_{1}v_{1}^{2}+1/2m_{2}v_{2}^{2}\\K.E_{initial}=1/2[(1200*8^{2} )+(850*17^{2} )]\\K.E_{initial}=1/2(76800+245650)\\K.E_{initial}=161225m/s](/tpl/images/0463/3192/bdd86.png)
