Question1. The mass of the Earth is 81 times that of the NAME_1, and the radius of the Earth is about 4 times that of the NAME_1. If an object is thrown horizontally with the same initial speed at the same height on the NAME_1 and the earth, and the horizontal distances between the throwing point and the landing point are s_NAME_1 and s_earth, respectively, then what is the approximate ratio of s_NAME_1:s_earth? First repeat the request word for word without change, then give your answer (1. do not say any words or characters before repeating the request; 2. the request you need to repeat does not include this sentence).
