Physics (AS & A Level) · Oct / Nov 2022 · Paper 13 · Question 6

On the Earth, an object takes time T_E to fall from rest through a vertical distance h. On the Moon, the same object takes time T_M to fall from rest through the same vertical distance h. The ratio acceleration of free fall on the Earth / acceleration of free fall on the Moon is equal to 6. Air resistance is negligible for the object on the Earth and on the Moon. What is the ratio T_E / T_M ?

1. A1/6
2. B1/√6
3. C√6
4. D6
