Ok, so the question is:(adsbygoogle = window.adsbygoogle || []).push({});

A 27-pound meteorite struck a car and created a dent about 22cm deep. If the initial speed of the meteorite was 550m/s, what was the average force exerted on the meteorite by the car?

Since this question is in the work/kinetic energy chapter I assumed I'd have to use:

W = 1/2mv_{f}^{2}- 1/2mv_{i}^{2}to find the work done and then use the equation:

W = F*x , solving for F using W from the above equation and x = 22cm

BUT then I realized the question was asking what force did the CAR exert on the METEORITE..and that's why I'm confused. Because solving it the way I originally thought would give me the force exerted by the METEORITE on the CAR, right? So now I have no idea what to do! Any hints/suggestions would be great! Thanks!!
