How Does Kinetic Friction Affect the Block's Motion on an Incline?

AI Thread Summary
The discussion focuses on calculating the effects of kinetic friction on a block sliding down an incline with a coefficient of kinetic friction of 0.30. The block starts with an initial speed of 7.0 m/s and slides 2.0 m before reaching the ramp. Participants are tasked with finding the block's speed upon reaching the ramp and the distance it slides on the incline before stopping. The conversation highlights the need to consider the friction force and the work done by this force in the calculations. Understanding these concepts is crucial for solving the problem effectively.

Homework Statement


Suppose that the surfaces described are not frictionless and that the coefficient of kinetic friction between the block and the surfaces is 0.30. The block has an initial speed 7.0m/s and slides 2.0 m before reaching the ramp. Find (a) the speed of the the block when it reaches the ramp, and (b) the distance the the block slides along the inclined surface before coming momentarily to rest.(Neglect and energy dissipated along the transition curve.)


Homework Equations


Not sure, this is where I am lost.

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...
