And, at the moment, I cannot answer your question.

AI Thread Summary
A 3.0 kg block accelerates down a 30-degree incline, moving 2.0 m in 1.5 seconds, prompting questions about its acceleration, coefficient of kinetic friction, frictional force, and final speed. To solve these, the discussion emphasizes understanding the forces acting on the block, particularly gravity and friction. It suggests considering the acceleration in a frictionless scenario to identify the effects of friction. Participants encourage formulating an initial attempt at a solution before seeking further assistance. The conversation highlights the importance of applying relevant physics concepts to solve the problem effectively.

You are pretty short on relevant equations and an attempt at a solution. Why don't you try to come up with something before you ask for help, please.
 
Welcome to PF.

What forces do you think are acting on the block?

There's always gravity. So how does it act on the block in moving it down the incline?

If it was frictionless what acceleration would it experience at that angle of incline? Armed with that and the acceleration they give you then maybe the friction effect could be identified?

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...
