Constraint Equations Homework: v0, v1, v2

Click For Summary
SUMMARY

The discussion centers on the relationship between the velocities of three blocks, specifically Block C moving with velocity v0, and Blocks A and B moving with velocities v1 and v2 relative to Block C. The conclusion drawn is that since the string is inextensible, the velocities of Blocks A and B must be equal, leading to the equation v1 = v2. The discussion also raises the question of whether to consider these velocities relative to Block C or the ground, with the consensus leaning towards using relative velocities to Block C for consistency.

PREREQUISITES
  • Understanding of classical mechanics principles, particularly relative motion.
  • Familiarity with the concept of inextensible strings in physics.
  • Basic knowledge of velocity and its vector nature.
  • Ability to analyze motion in a multi-body system.
NEXT STEPS
  • Study the principles of relative motion in classical mechanics.
  • Explore the concept of inextensible strings and their implications in physics problems.
  • Learn how to apply Newton's laws of motion in multi-body systems.
  • Investigate the differences between relative and absolute velocity measurements.
USEFUL FOR

Students studying classical mechanics, physics educators, and anyone interested in understanding the dynamics of multi-body systems and relative motion.

The Attempt at a Solution


Since the string is in-extensible, its velocity at both ends should be equal. So v1=v2
But should i take the velocity with respect to Earth instead of velocity with respect to block? Both gives me different answers.

So v01=v2
Did you mean v1=v2?
What do you think - should it be the speeds relative to the block that are equal or speeds relative to the ground?
 
The string itself has a velocity v0 if A and B are at rest. Then if A acquires a velocity v1, then B should also have a velocity v1.
