Hint: Use 1D relative velocity to find the velocity of the car
with respect to the air, which is used to find the drag force.
A 2520 lb car has a frontal cross-sectional area A of 20.0 ft2, a drag coefficient Cd of 0.25, and a drive (or tractive) force of 250 lbs. Assume an air density of 2.3x10-3 slug/ft3, Here is a list of frontal areas and drag coefficients for cars. This web site has interesting information on how...

Can anyone do part E, please?
Hint #1:
Find required acceleration using constant acceleration
equations.
Hint #2:
Use FBD of entire train.
The EF Express, a train similar to the one shown above, has 3 locomotives (71 tons each) and 75 coal cars (32 tons each). The train is going down a 1.1% incline. Use positive as the direction the train is going This problem DOES need to be written out for your Rortfoli A complete FBD-KD for each of...
