How can I calculate the acceleration in this system?

Click For Summary
SUMMARY

The discussion focuses on calculating the acceleration of a system involving two blocks, m1 and m2, in an accelerating elevator. It highlights that when the elevator accelerates upwards with acceleration 'a', the effective weight reading on a scale will be m(g + a). The forces acting on each block must be considered to derive the acceleration accurately. The conversation emphasizes using variables instead of numerical substitutions to understand the underlying physics principles.

PREREQUISITES
  • Understanding of Newton's laws of motion
  • Familiarity with basic concepts of forces and acceleration
  • Knowledge of gravitational force calculations
  • Experience with variable manipulation in physics equations
NEXT STEPS
  • Study the principles of Newton's second law of motion
  • Learn about tension in ropes and its effects on acceleration
  • Explore the concept of effective weight in non-inertial reference frames
  • Investigate pulley systems and their dynamics in physics
USEFUL FOR

Students of physics, educators teaching mechanics, and anyone interested in understanding dynamics in non-inertial frames, particularly in systems involving pulleys and acceleration.

First of all, consider one block of them, and using only variables (don't substitute with numbers), try to find its acceleration.
Hint : What forces are acting upon each block?
 
Alternatively, if you are in an elevator accelerating up with acceleration ##a## and you stand on a scale, your weight reading will be ##m(g+a)##. Now imagine the pulley being attached to the ceiling of this elevator and you put ##m_1## and ##m_2## on the scale before attaching them to the rope. What would the scale read? Therefore, ...
