A small meteorite (30 kg) is fallingthrough the earth’s atmosphere. It is moving very fast - in fact,faster than the terminal velocity it would have reached if had beendropped from a great height. In a situation like this, thedrag force is stronger than the weight. At one moment, themagnitude of the meteorite’s acceleration is 4.0m/s2. You need to calculate the magnitude of the dragforce on the meteorite.
- Draw a free-body diagram, which includes an arrow for eachindividual force on     the meteorite (andlabels to indicate the type of force), an arrow for thenet force,     and a coordinatesystem.    Â
- In this situation, the velocity of the meteorite and theacceleration of the meteorite point in [the same direction,in opposite directions].
- In this situation, the velocity of the meteorite and the netforce on the meteorite     point in[the same direction, in opposite directions].
- In this situation, the magnitude of the drag force on themeteorite is [increasing, Â Â Â Â decreasing, remailing constant].
- Write an algebraic expression that shows how the individualforces combine to     produce the net force onthe meteorite. The signs in the expression must be
             consistent with the coordinate system in the free-body diagram.(That is, add in     all the forces in thepositive direction and subtract all the forces in the negative    direction.)
- Set that expression equal to ma and solve theresulting equation for the
             magnitude of the drag force. Type out the equation with all knownnumbers     inserted in their proper placesand then just state the answer.
