Okay, seeing that I'm new, I'll just tell everyone who reads this that I am a freshman in college, second semester, and am in Introductory Physics. Unfortunately, I've never taken a physics course before, and no science period since Junior year in HS.
My professor posts online quizzes each week, and I am taking my second one. Each one has four questions, 5 points each, I've solved two of them correctly, but I have no idea where to start on this one:
A 4000 kg van traveling at 24.0 m/s collides with a 2000 kg car that is stopped at a traffic light. Their bumpers become entangled, and they move forward together. What is their speed immediately after the collision?
The only work I have to show for it are the masses, velocities, and accelerations of each car (which is pretty easy to find). I know we're supposed to show more work, but I am pretty lost as to how to even go about this question. If someone could please just point me in the right direction on where to go with this it would be greatly appreciated. Thank you
