How Does Gravity Affect the Maximum Height of a Thrown Ball?

[needhelp?]

Q1. A ball was thrown vertically into the air at a speed of 30m/s
a) Calculate the maximum height of the ball.
b) If the same ball was thrown on the Moon where gravity is one sixth of the gravity on Earth, what would be the maximum height now?

Just wondering... does the mass of the ball have any effect on the result(s)?
