Solving the Atwood Machine - Descending Mass

Click For Summary
SUMMARY

The discussion focuses on solving the Atwood machine problem involving two masses, m1 = 2.20 kg and m2 = 7.30 kg, with negligible pulley and string mass. The initial downward velocity of m1 is 2.70 m/s. The tension in the system is calculated to be 33.1 N. Participants discussed applying kinematics of uniformly accelerated motion to determine how far m1 descends before its speed reaches zero.

PREREQUISITES
  • Understanding of Newton's laws of motion
  • Familiarity with kinematics equations for uniformly accelerated motion
  • Basic knowledge of tension in a pulley system
  • Ability to perform calculations involving forces and acceleration
NEXT STEPS
  • Study the kinematic equations for uniformly accelerated motion
  • Learn about the dynamics of Atwood machines
  • Explore the concept of tension in different pulley systems
  • Investigate the effects of friction on pulley systems
USEFUL FOR

Physics students, educators, and anyone interested in mechanics, particularly those studying dynamics and kinematics in systems involving pulleys and masses.

In the Atwood machine regular 2 mass machine,m1= 2.20kg and m2=7.30kg . The masses of the pulley and string are negligible by comparison. The pulley turns without friction and the string does not stretch. The lighter object is released with a sharp push that sets it into motion at an initial velocity of 2.70m/s downward. I found the Tension to be 33.1N, but i don't understand how to apply to find how far will m1 descend below its initial value? Could anyone help me out?

Find the acceleration of the masses, which for m1 will be upward. Use the kinematics of uniformly accelerated motion to find out how far m1 descends before coming back up. Hint: Find the point where its speed is zero.
 
i figured it out thanks for the suggestion. Closed!
