Two cars collide at an icy intersection and stick together afterward. The first car has a mass of 1050Kg and was approaching at 8.00m/s due south. The second car has a mass of 700Kg and was approaching at 20.0m/s due west.
A) Calculate the final velocity of the cars.(Note that since both cars have an initial velocity, you cannot use 7.6a and b. You msut look for other simplifying aspects.)
_______m/s
B) How much kinetic enregy is lost in the collision? (This energy goes into deformation of the cars.)
________J

This figure shows an overhead view of the path of a 0.187 kg ball as it bounces from a rail of a pool table. The ball’s initial speed is 2.19 m/s. The angle θ1 shown on the sketch is 30.0o. The bounce exactly reverses the y component of the ball’s velocity but the x component is unchanged.
What is the angle θ2 equal to?
