Out of curiosity, If suppose a car is driven/propelled by Propeller, how much thrust would be required to get it rolling or moving, then drive at 30 MPH, at 60 MPH and at 100 MPH? Consider the car weighs 6000 lb including passengers. If same car is inclined at 30 degrees, how much thrust is required to move it forward. What could be the formula to formulate this relationship of thrust and speed etc? Assume all standard road conditions.
