SUMMARY

The discussion centers on calculating the gravitational acceleration on the Moon based on the distances a golf ball travels under identical conditions on Earth and the Moon. The golf ball travels 30 meters on Earth and 180 meters on the Moon, leading to the conclusion that the gravitational acceleration on the Moon is significantly lower than on Earth. The relevant equations for projectile motion are applied, specifically focusing on the relationship between distance, gravity, and time of flight.

PREREQUISITES
  • Understanding of projectile motion principles
  • Familiarity with gravitational acceleration concepts
  • Knowledge of kinematic equations
  • Basic algebra for solving equations
NEXT STEPS
  • Study the kinematic equations for projectile motion
  • Learn how to derive gravitational acceleration from distance traveled
  • Explore the differences in gravity between celestial bodies
  • Investigate the effects of launch angle on projectile distance
USEFUL FOR

Students in physics courses, educators teaching projectile motion, and anyone interested in understanding the effects of gravity on different celestial bodies.

Homework Statement


you hit a golf ball 180m on the moon, but on Earth you only hit it 30m. Assuming that everything is the same (swing, launch angle, etc..) find the gravity of the moon.


Homework Equations


a = -g (on earth)
Xe = 30m
Xm = 180m


The Attempt at a Solution



I really don't know where to tackle this problem from. I need assistance.

It is projectile motion, the same magnitude and angle of initial velocity, only the value of g is different. How long is the projectile above ground? What is the horizontal distance the projectile travels during this time?
