The problem involves a ballistic pendulum setup where a projectile collides with a pendulum block. The goal is to determine the initial velocity of the projectile based on the height reached by the pendulum after the collision.
The discussion includes attempts to verify an initial velocity calculation, with some participants questioning the correctness of the answer provided. There is a recognition that conservation of energy may not apply, suggesting a shift towards considering momentum instead.
Participants note the need to ignore friction in the calculations, which is a relevant constraint in the problem setup.
No, I'm afraid your answer is incorrect.uvburgos said:I do have the answer just need verify is my answer is correct (Vi=3.6m/s)
This doesn't change the answer. Your solution is still incorrect, conservation of energy does not apply here. You must you conservation of momentum.uvburgos said:I forget to write at the end to ignore the friction
