If a constant force of 200 N is applied to the car what is its terminal velocity ?  - Microsoft Word.png)
A car rolling on a hill can be modeled as shown in Figure E-25. The excitation is the force for which a positive value represents accelerating the car forward with the motor and a negative value represents slowing the car by braking action. As it rolls, the car experiences drag due to various frictional phenomena that can be approximately modeled by a coefficient which multiplies the car’s velocity to produce a force which tends to slow the car when it moves in either direction. The mass of the car is m and gravity acts on it at all times tending to make it roll down the hill in the absence of other forces. Let the mass m of the car be 1000 kg, let the friction coefficient be and let the angle be .
