Confirm Calculation of Bullet Velocity to Hit Skeet

Click For Summary

Homework Help Overview

The discussion revolves around calculating the initial velocity of a bullet required to hit a skeet moving at a specified speed. The context involves projectile motion and relative velocities in a physics problem.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the distance the bullet must travel compared to the skeet's movement and question whether the problem is one-dimensional or involves angles. There are varying initial velocity estimates provided.

Discussion Status

The discussion is ongoing, with participants sharing different calculations and questioning the assumptions about the problem's dimensionality. Some guidance has been offered regarding the relationship between the bullet's speed and the skeet's movement.

Contextual Notes

There is uncertainty regarding the dimensionality of the problem, as skeet are typically fired at an angle, which may affect the calculations. Participants are also considering the implications of their assumptions on the accuracy of their answers.

A skeet is shot at 25.0 m/s [H 75 U], 2 seconds later the rifleman shoots, striking the target in .4s. What initial velocty of the bullet is needed for it to hit the skeet?

I just need someone to confirm the answer I have. It's probably way off but I got 191 m/s [H 78 U]


thanks.

The bullet must travel the same distance as the skeet does.
The speed I got was a bit smaller.
 
Is this a one dimensional problem or what? Skeet are fired at an angle...

The numbers sound about right for... roughly 350 mph is an ok bullet speed (kinda on the lower end however)

I assumed it is one dimensional. If it isn't, my help is of course incorrect.
 
answer is smaller
