9. A physics student decides to “burn off” some Calories by climbing a ladder. As the ladder is ascended, some food energy is being converted to gravitational potential energy. (a) If the student has a mass of 75 kg, how tall a ladder is needed to burn off one Calorie (4190 J)? (b) Conversely, if the student only has a 3.5 m ladder, how much additional mass must he carry up with him to burn off the Calorie?
