Exam review question (acceleration)

Click For Summary
SUMMARY

The discussion revolves around calculating the acceleration of two combined masses under the influence of a constant force. A force of 1 N applied to mass m1 results in an acceleration of 1.0 m/s², while the same force applied to mass m2 yields an acceleration of 3.00 m/s². The key equation used is Newton's second law, F = m*a, which allows for the determination of the combined acceleration when both masses are subjected to the same force. The solution requires calculating the total mass and applying the formula to find the new acceleration.

PREREQUISITES
  • Understanding of Newton's second law (F = m*a)
  • Basic knowledge of mass and acceleration concepts
  • Ability to manipulate algebraic equations
  • Familiarity with units of force (Newtons) and acceleration (m/s²)
NEXT STEPS
  • Study the implications of combining masses in physics problems
  • Learn how to derive acceleration from force and mass in various scenarios
  • Explore examples of force and acceleration calculations in different contexts
  • Practice solving problems involving multiple forces and masses
USEFUL FOR

Students preparing for physics exams, educators teaching Newtonian mechanics, and anyone seeking to enhance their understanding of force and acceleration relationships.

Homework Statement



A force of 1 N pushing on a mass m1 results in an acceleration of 1.0 m/s2. The same force acting on mass m2 results in an acceleration of 3.00 m/s2. What is the acceleration a3 for the same force pushing the combination of m1 and m2?

Homework Equations



well I know that acceleration = force/mass lol

The Attempt at a Solution



this is a example problem for my first test tomorrow morning.. honestly I don't have a clue how to solve this problem and a good explanation would be very helpful.

two other problems from the exam review

ACCELERATIONS for SAME FORCE on DIFFERENT MASSES

A force F acting on a mass m1 results in an acceleration a.
The same force F acting on mass m2 results in an acceleration 0.20 a.
What is the acceleration anew for F pushing the combination of m1 and m2?

A force F of 3 N acting on a mass m1 results in an acceleration of 1 m/s2.
The same force F acting on mass m2 results in an acceleration of 0.20 m/s2.
What is the acceleration a3 for F pushing the combination of m1 and m2?
 
Physics news on Phys.org
Well we know that:
[tex]\vec{F}=m\vec{a}[/tex]
What is m in this situation?
What is the total mass?
 
do you combine the masses? i mean really i don't have a clue how to solve this problem
