Determine what is the drag coefficient at sea level

Reference no: EM13309404

A 2,150 lb car is traveling at sea level at a constant speed. Its engine is running at 4500 rev/min and is producing 150 ft-lb of torque. It has a driveline efficiency of 90%, a driveline slippage of 2%, 15-inch radius wheels and an overall gear reduction ratio of 3 to 1. If te car's frontal area is 19.4 ft2, what is the drag coefficient?

Hint: it is important to keep track of all known values and the handful of equations that related them. Ultimately you should be able to solve for a vlaue of Fe, V, frl, Rrl. With these solved (plus a few given values) you should be able to use another equivalency for F_e that allows you to solved for C_D.
