A blue car with a mass of mcar = 2900 kg and a yellow truck with mass mtruck = 9300 kg enter an intersection. The truck comes from the south at vtruck = 7 m/s, and the car comes from the west. When the two collide they stick together and slide at an angle of ? = 43° north of east. what is the speed of the pair after the collision? what is the eastward component of the momentum of the pair after the collision? At what speed was the car traveling before the collision? What is the kinetic energy of the pair before the collision? What is the kinetic energy of the pair after the collision?
For this one I think I have the first 3 questions done but need to know if i have them right, for the last 2 I have no idea where to start. help?
