SUMMARY
The power required to move a 3000 lb car up an 8-degree incline at a constant speed of 50 mi/h against a frictionless force of 80 lb is calculated to be 68 horsepower. The calculation utilizes the formula P = Fv, where the force includes both the gravitational component and the frictional force. The final result confirms that the power needed is approximately 66.34 horsepower, aligning with the established calculations presented in the discussion.
