A bullet goes through a ballistic pendulum, what is it's initial velocity?

Click For Summary
SUMMARY

The discussion centers on calculating the initial velocity of a 7.0-g bullet that passes through a 1.5-kg ballistic pendulum. The bullet exits the pendulum at a speed of 200 m/s, and the pendulum rises to a height of 12 cm. The solution involves applying the conservation of momentum principle, particularly for glancing collisions, to determine the bullet's initial speed before impact.

PREREQUISITES
  • Understanding of conservation of momentum in physics
  • Familiarity with ballistic pendulum mechanics
  • Ability to convert units to SI units
  • Knowledge of energy conservation principles
NEXT STEPS
  • Study the conservation of momentum in glancing collisions
  • Learn how to analyze ballistic pendulum problems
  • Review the conversion of units in physics calculations
  • Explore the relationship between potential energy and maximum height in pendulum motion
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and momentum, as well as educators seeking to clarify concepts related to ballistic pendulums and energy conservation.

Homework Statement


A 7.0-g bullet is fired into a 1.5-kg ballistic pendulum. The bullet emerges from the block with a speed of 200 m/s, and the block rises to a maximum height of 12 cm. Find the initial speed of the bullet.


Homework Equations


Conservation of Momentum


The Attempt at a Solution


I first converted all of my units into SI units. I then went to use the Conservation of Momentum for Glancing Collisions, with X and Y components, but I am confused as to what the components of the bullet are. All I know is that the pendulum rises at some angle to .12 m above it's original position and I'm not sure how to interpret this into an equation. Any assistance will be greatly appreciated.

Is it necessary to do this with Cons of momentum as Cons of energy seems easier?
