Ballistic Pendulum Experiment: Determining Muzzle Velocity and Projected Height

Click For Summary
SUMMARY

The forum discussion centers on calculating the muzzle velocity of a ball bearing in a ballistic pendulum experiment, with a determined value of Vmuzzle = 1.247 m/s. The user seeks assistance in predicting the maximum height the ball bearing would reach when fired vertically, utilizing principles of projectile motion. Key concepts include kinematics and conservation of energy, which are essential for solving the height calculation based on the initial velocity derived from the muzzle velocity.

PREREQUISITES

Calculate the most reasonable muzzle velocity of the ball bearing given:

Mass of Bearing = .033kg
Mass of the Combination = .064kg
Length of Pendulum = .235m
Theta = 24 degrees


I was able to solve that and get Vmuzzle = 1.247 m/s^2

The second part of the question is what I'm having trouble with.

If we were to devise an experiment to check that the above muzzle velocity is correct by firing the bearing straight upwards, what height would you expect the bearing to reach (most reasonable)?

I'm pretty sure I can figure this out once I get a starting point. We covered this section in lab before lecture and I wasn't able to find a similar example looking ahead in the book to base a solution on.

Thanks!

The second part is a projectile motion problem. What's the initial velocity? The acceleration? Use kinematics. (You can also use conservation of energy, if you like.
 
Got it! Thanks Doc!
