Coefficient of static friction of a sliding block

AI Thread Summary
To determine the speed of a block sliding down a ramp with a height of 1.610m and an angle of 39.4 degrees, the coefficients of kinetic and static friction are given as 0.111 and 0.173, respectively. The net force acting on the block halfway down the ramp needs to be calculated, and the appropriate equations include F = ma and the frictional force equations. Participants emphasize the importance of showing an attempt at solving the problem, such as drawing a free body diagram, to facilitate assistance. Understanding the forces at play, including gravitational and frictional forces, is crucial for solving the problem. Engaging with the community by providing initial calculations can lead to more effective guidance.

Homework Statement



block is placed on a ramp at an angle of 39.4 and height of the ramp is 1.610m and the mass of the block is 8.54kg
if coefficient of kinetic friction is 0.111 and the coefficient of static friction is 0.173 what is the speed of the block at the bottom of the ramp. if it started from the rest at the top of the ramp

magnitude of the net force on the block half way down the ramp


Homework Equations



Dont know how to approach these questions
which equations would be most appropriate?

What equations do you know?

F = ma .

f = μkN

f ≤ μsN


You really need to show an attempt before we can help you. For one thing. that is a rule for these forums.
 
Why don't you start by drawing a free body diagram and posting it?

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...
