The roads are icy, and you observe a head-on collision on Summit, at the corner with Rhodes: a 1 ton car swerves out of his lane and slides through a stop sign at 40 mph straight into a 3 ton SUV traveling at 11 mph in the other direction. The car and the SUV crumple from the collision, and stick together. What is the final velocity, in MPH, of the SUV/car entanglement (the positive direction is the direction the car was initially going)?

2. In a head-on collision between a truck (object #1) and a car (object #2), as difficult as it is to believe, the force of the truck on the car is equal (and opposite in direction) to the force of the car on the truck. However, because of their different masses, the two vehicles have very different subsequent motion: the truck basically keeps going, while the car will get smashed up and stick to the front of the truck. Another...
