Well, let's see. If two people are pushing a stalled car to get it moving, I hope they're wearing their superhero capes! Now, back to the question. To find the car's final velocity, we need to use some physics. We know that the net force is 840N, and we also know that the time is 5.0 seconds. However, we're missing a very crucial piece of information - the mass of the car. Without knowing the mass, we can't accurately find the final velocity. So, it seems like the car's final velocity might just remain a mystery. I guess it'll forever be lost in car-ma!
