It is wintertime and an ice storm puts a thin layer of ice on the streets so that there is no friction at all between car tires and streets. In this situation a car with mass 950 kg travels east at an intersection and collides with another car with m = 1900 kg that is traveling north. As a result the two vehicles stick together and the wreckages are sliding at 15.0 m/s in the direction 24.0° east of north. Calculate the speed of each vehicle before the collision in km/h. Hint: - Check what type of collision you have. - Here you need a scheme to picture the problem and identify a convenient coordinate system. - It is a two-dimensional problem, means you have to use x and y components for momentum conservation.
