So we're going to say that the move, the astronaut throws the ball straight up so we can straight up on the moon so they'll be 90 degrees s o. We can say that. Why, Max, they're going to be equal to the initial sign of Seita squared, divided by two G and this is simply going to both of the initial squared divided by two G. Given that sign of data is going to equal one. And so we can say that why Max is going to be directly proportional, rather inversely proportional to one over G. And so we can say that why, Max on the moon, divided by why Max on the Earth is going to be equal to the gravity on the earth divided by the gravity on the moon. And we know that the gravity on the earth equals six times the gravity on the moon. So we can say that why Max on the moon is simply going to be equal to six times why Max on earth. Now we know that the Y Max on earth is five meters, so essentially 56 times five when you call 30 meters. So this would be the answer, and we know that the correct answer. His choice. See, that is the end of the solution. Thank you for watching.
