SUMMARY

The discussion centers on calculating the speed required to throw a baseball into orbit on Deimos, a moon of Mars. Using the formula v^2 = GM/R, where G is the gravitational constant (6.67×10^-11), M is the mass of Deimos (2.00×10^15 kg), and R is the radius (6.0 km), the calculated orbital speed is approximately 3.334 m/s. This speed ensures that the baseball would return to the thrower after being pitched. The conversation also includes a light-hearted exchange about the difference between radius and diameter.

PREREQUISITES
  • Understanding of gravitational physics and orbital mechanics
  • Familiarity with the gravitational constant (G)
  • Knowledge of basic algebra and square root calculations
  • Concept of mass and diameter in celestial bodies
NEXT STEPS
  • Explore the implications of low gravity on projectile motion
  • Learn about orbital mechanics and escape velocity calculations
  • Study the properties of celestial bodies, focusing on moons like Deimos
  • Investigate the effects of gravity on sports and projectile trajectories
USEFUL FOR

Students of physics, educators in astronomy, and enthusiasts interested in the mechanics of motion in low-gravity environments.

1. Deimos, a moon of Mars, is about 12.0 in diameter, with a mass of 2.00×1015 . Suppose you are stranded alone on Deimos and want to play a one-person game of baseball. You would be the pitcher, and you would be the batter!

With what speed would you have to throw a baseball so that it would go into orbit and return to you so you could hit it?



2. v^2=GM/R



3.v = sqrt(6.67*10^-11*2*10^15/12000)
v = 3.334 m/s

Hi PhysicsScrub, Welcome to Physics Forums.

What's the difference between radius and diameter? :wink:
