Two cars with no brakes or motor, and with no axle friction or body drag, are allowed to roll down a hill under the sole power of their weight (gravity). Both cars have the same total mass and both start at rest at the top of the hill. Car A descends a 50ft-tall hill that has a 5-degree incline; Car B descends a 50ft-tall hill that has a 25-degree incline. Both descend to the bottom of their respective hill, at which time their speed are compared. Which one of the following statements is correct? A. Car A and Car B will travel at the same speed B. Car A will travel faster than Car B C. Car A will travel slower than Car B D. None of the above is true
