How Do You Calculate the Mass of Object 2 After a Collision?

Click For Summary
SUMMARY

The discussion focuses on calculating the mass of Object 2 after a collision using the principle of conservation of momentum. Given that Object 1 has a mass of 2.8 kg and an initial velocity of 7.7 m/s, and after the collision, it recoils with a velocity of -2.2 m/s, the equation m1v1 = m2v2 is applied. By rearranging the equation, the mass of Object 2 can be determined as m2 = (m1 * v1) / v2. This method effectively illustrates the application of momentum conservation in collision scenarios.

PREREQUISITES
  • Understanding of conservation of momentum principles
  • Familiarity with basic physics equations related to motion

Homework Statement



Object 1 has a mass of 2.8 kg and is moving eastward with a velocity of 7.7 m/s. It collides with a stationary object. After the collision object 1 recoils with a velocity of -2.2 m/s What is the mass of object 2?

Homework Equations



As far as I know:

Conservation of Momentum
Po=P
m1v1=m2v2
m=mass

The Attempt at a Solution



I keep trying to solve by using m1v1=m2v2

m2 = m1v1/v2

What does the momentum equation you've written (m1 v1 = m2 v2) mean (in words)?
