Accelaration Angle Force Motion Motion in 1d Motion in 2d Net Net force Newton's second law

AI Thread Summary

To determine the acceleration in two-dimensional motion, the horizontal component of the net force is divided by the mass. The calculated value of 0.4 m s^-2 is confirmed as correct. The discussion emphasizes the importance of resolving forces into components for accurate calculations. Overall, the method used to find acceleration from net force is validated. This approach is essential for understanding two-dimensional motion dynamics.

Yes, it is.

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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
