Answer:
hmax = 181.48m
Explanation:
In order to calculate the maximum height reached by the same ball in the moon, you first calculate the initial velocity of the ball by using the information about the maximum height on the Earth. You use the following formula:
(1)
hmax: maximum height reached by the ball in the Earth = 30m
vo: initial velocity of the ball = ?
g: gravitational acceleration on Earth = 9.8m/s^2
From the equation (1) you solve for vo:

Next, you use the same equation (1) but for the gravitational acceleration of the moon, which is given by:
g' = 1.62m/s^2

The same ball, with the same initial velocity, will reache a heigth of 181m in the moon.
