SUMMARY

The discussion focuses on calculating the force exerted by a spaceship on an astronaut during lift-off from the planet Zuton. The astronaut's weight on Earth is 726.6 N, and the free-fall acceleration on Zuton is 7.8 m/s², while the spaceship's acceleration is 9.1 m/s². Using Newton's second law, the mass of the astronaut can be determined as 74.1 kg (calculated from the weight on Earth), which is then used to find the force exerted by the spaceship, resulting in a total force of 757.5 N acting on the astronaut during lift-off.

PREREQUISITES
  • Understanding of Newton's second law of motion
  • Knowledge of weight and mass relationship
  • Familiarity with gravitational acceleration concepts
  • Basic calculations involving force and acceleration
NEXT STEPS
  • Study Newton's second law of motion in detail
  • Learn about gravitational forces on different celestial bodies
  • Explore the concept of weightlessness in space travel
  • Investigate the effects of acceleration on human physiology during spaceflight
USEFUL FOR

Physics students, educators, and anyone interested in introductory physics concepts related to forces and motion in space environments.

Ok I really just don't even know where to start on this problem and i have to turn in a fully explained problem...

An astronaut who weighs 726.6 N on the surface of the Earth lifts off from the planet Zuton in a space ship. The free-fall acceleration on Zuton is 7.8 m/s^2. At the moment of lift off the spaceship experiences an scceleration of 9.1 m/s^2.
The acceleration of gravity is 9.8m/s^2. What is the magnitude of the force that the spaceship exerts on the astronaut? Answer in units of N.
 
Physics news on Phys.org
You know that the mass of the astronaut has to be the same on any planet. You have the weight of the astronaut on Earth given to you. You know the acceleration of gravity. Use the second law of Newton to find the mass of the astronaut first.

P.S : This question should be under introductory physics, not advanced physics.
