Two masses are connected by a string and pulled along a frictionless surface by anoth

Click For Summary
SUMMARY

The discussion centers on a physics problem involving two connected masses of 5 kg and 10 kg, subjected to a tension of 40.0 N on a frictionless surface. The correct calculation for the system's acceleration is derived using the formula a = F/m, where F is the total force and m is the total mass. The total mass is 15 kg, leading to an acceleration of 2.67 m/s², confirming that option D (2.7 m/s²) is indeed the correct answer.

PREREQUISITES
  • Understanding of Newton's Second Law of Motion
  • Basic knowledge of mass and force concepts
  • Familiarity with the equation a = F/m
  • Concept of tension in connected systems
NEXT STEPS
  • Study advanced applications of Newton's laws in multi-body systems
  • Explore the effects of friction on acceleration in real-world scenarios
  • Learn about tension forces in pulleys and inclined planes
  • Investigate the principles of dynamics in non-frictionless environments
USEFUL FOR

Students studying physics, educators teaching mechanics, and anyone interested in understanding dynamics and forces in connected systems.

17. Two masses are connected by a string and pulled along a frictionless surface by another
string one is 5kg and the other is 10 kg to which a tension of 40.0 N is applied. The magnitude of the system’s acceleration
is
A. 8.0 m/s2
B. 20 m/s2
C. 13 m/s2
D. 2.7 m/s2
(For this question I added the two masses to get the mass and then I used the equation a=f/m to find the acceleration)

Is D. the correct answer?
