SUMMARY

The discussion revolves around a physics problem involving the collision of a 10 kg object with a 30 kg object, where the 10 kg object is said to accelerate at 60 m/s. Participants clarify that the term "acceleration" is misused, as 60 m/s represents speed, not acceleration. The correct approach to solve this problem involves the principle of conservation of momentum, which requires additional information about the collision type (whether the objects stick together or rebound) to provide a definitive answer.

PREREQUISITES
  • Understanding of Newton's Second Law (F=ma)
  • Knowledge of conservation of momentum principles
  • Familiarity with units of measurement (meters per second vs. meters per second squared)
  • Basic concepts of elastic and inelastic collisions
NEXT STEPS
  • Study the principles of conservation of momentum in collisions
  • Learn about elastic vs. inelastic collisions and their characteristics
  • Review Newton's laws of motion, particularly the second law
  • Practice solving collision problems with varying masses and velocities
USEFUL FOR

This discussion is beneficial for students studying physics, educators teaching mechanics, and parents assisting children with science homework related to motion and collisions.

We are lost, trying to help daughter with science work. "If a 10 kg object collides with a 30 kg object and the 10 kg one accelerates at the rate of 60m/s, what was the acceleration of the 30 kg object?"
?? We arent sure what to do, what formula to use, if its f=mass X acceleration or what... is it 10 kg x 60 m/s?

Welcome to the forums.

To be honest, stated like this the question does not make sense.
First, an acceleration is in meter per second squared, so the 60m/s number you are giving either has the wrong units or it is a speed, not an acceleration.

This sounds much more like a problem of conservation of momentum but there is not information supplied to even start answering the question. Do the objects stick together or do they rebound?

Is it possible to write down the question exactly as it was formulated?
