Conservation of energy, A bomb explodes into three pieces

AI Thread Summary
The discussion focuses on solving a physics problem involving the conservation of momentum after a bomb explosion that produces three pieces. Two pieces with equal mass travel at 100 m/s at a 60-degree angle to each other, while the third piece has three times the mass of the others. The user calculates the direction of the third piece to be 150 degrees and attempts to find its velocity using momentum conservation equations. Responses confirm that the calculations appear correct, but the user expresses some uncertainty about the solution. The conversation emphasizes the importance of correctly applying conservation principles in explosive scenarios.

Homework Statement


A bomb explodes into three pieces, two have an equal mass and fly off at 60 degress to one another with the speed of 100 m/s. The third piece has three times the mass of each of the other pieces. Find the direction and magnitude of the third piece immediatly after the explosion



Homework Equations


Is my solution correct?
If not, how should I re-approach the problem


The Attempt at a Solution


2A + 60 = 360
2A = 300
A = 150 degres, A is the direction of the third angle

2*100m/s cos(180-150)-3mv = 0
200/3cos(30)
57.7

Yes, that looks ok …

what is worrying you about that? :confused:​

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
