Determining Coefficient of Kinetic Friction (mew)

AI Thread Summary
To determine the coefficient of kinetic friction (mew) for a box sliding down a 31-degree ramp with an acceleration of 1.42 m/s², it is essential to analyze the forces acting on the box. A free body diagram (FBD) should be drawn to identify the weight, normal, and friction forces. Applying Newton's laws in both the x (parallel to the ramp) and y (perpendicular to the ramp) directions will help in solving the problem. The equations F=ma and Fnet=ma are crucial for this calculation. Properly setting up the problem will lead to the correct determination of the coefficient of kinetic friction.

Homework Statement


A box slides down a 31 degree ramp with an acceleration of 1.42 m/s squared. determine the coefficient of kinetic friction (mew) between the box and the ramp.


Homework Equations


F=ma Fnet=ma Fn(µ)=Ff


The Attempt at a Solution


Many attempts on paper but unable to show on this.
 
Physics news on Phys.org
Please show one of your attempts so we may better assist. You need to draw a FBD of the box identifying the weight, normal, and friction forces acting on it,,,,,,,look up 'inclined planes'...and for simplicity choose the x-axis as parallel to the plane and the y-axis as perpendicular to the plane..and Apply Newton's laws in the x and y directions.

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 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
