SUMMARY

The discussion centers on calculating the movement of a 60kg canoe when a 45kg woman walks from one end to the other. The scenario is analyzed using principles of conservation of momentum and center of mass. As the woman moves from a point 1m from one end to 1m from the other end, the canoe will shift in the opposite direction. The final calculation reveals that the canoe moves a distance of 1.5m during this process.

PREREQUISITES
  • Understanding of conservation of momentum
  • Basic principles of center of mass
  • Knowledge of action-reaction forces
  • Familiarity with kinematic equations
NEXT STEPS
  • Study the principles of conservation of momentum in closed systems
  • Explore calculations involving center of mass in multi-body systems
  • Learn about action-reaction pairs in physics
  • Investigate kinematic equations for motion analysis
USEFUL FOR

Physics students, educators, and anyone interested in understanding the dynamics of movement in systems involving multiple bodies.

i'm having a problem with this one:
45kg woman is in a 60kg canoe of length 5m. They are initially at rest. she walks from a point 1m from the end to a point 1m from the other end where she stops. If resistance and the motion of the canoe in the water are ignored, how far does the canoe move during the process.

I thought this was a center of mass problem, but the center of mass doesn't change because the woman begins at rest. i don't know where to start...

How about conservation of momentum?

Hint: the magnitude of velocity (speed) = distance/time, and the time is the same.

Action-reaction.
