Acar with a mass of 975 �� and a speed of 18.0 �/� approaches an intersection from west. a 1260 �� minivan traveling at 25.8 �/� due north is heading for the same intersection. the car and minivan collide and stick together. (a) state two equations that will satisfy the conversation of linear momentum. (b) find the speed and direction of the wrecked vehicles just after the collision, assuming external forces can be ignored.
