attach a known weight to a string through the pulley to another known weight on the table-top. How do you find the acceleration of a box sliding down a slope with friction, without knowing its mass?
Coefficient of static friction will get cancelled out. by Ron Kurtus (revised 21 November 2016) The goal of this experiment is to measure the static sliding coefficient of friction between two surfaces by using a ramp and measuring its inclination.. Objective: To determine the coefficient of kinetic friction between two selected surfaces by using a horizontal surface.
An easy way to measure the coefficient of static friction is to place two objects together and then tilt them until the top one slides.
They answered your questions >> How have things changed for you during Covid-19? You’re pushing a box of books with a mass of 25 kg up a 40-degree ramp. A force of 40.0 N accelerates a 5.0-kg block at 6.0 m/s^2 along a horizontal surface. Gravitational Potential Energy Q M1 Dynamics question The box has a mass of 75.0 kg, and the worker is exerting a force of 400.0 Nforward.What is the magnitude of the force of friction, and what is the net force moving the box?
Is there any way to calculate the coefficient of friction in … Coefficient of friction help!

Stack Exchange Network Stack Exchange network consists of 175 Q&A communities including Stack Overflow , the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. M1 is being pulled one way. The problem goes as follows. start new discussion reply. When the two objects are horizontal there is no frictional force. To find normal force, you need mass and a velocity vector. Find the coefficient of friction between the particle and the plane. I have looked up the formula, but I do not understand how to use it without having mass. The angle at which one object starts to slip on the other is directly related to the coefficient. M1 Calculating the coefficient of friction Help Needed? How do you work out the coefficient of friction without the mass???? Any help with this would be greatly appreciated.
Resolving up the plane: F - 5gsin30 = 0. You can't; there's not enough information. We can find friction everywhere in our surroundings. The coefficient of kinetic friction is μ k = 0.520. This tells you the maximum force of friction for these materials, and physicists describe this through the coefficient of static friction (μ static).
Calculate the force required to accelerate the body. So far I have done the following: F = ma F = (925)(-12.2) F = -11285N. This is the problem given: A block with an initial velocity of 3 m/s slides 9 m across a rough horizontal surface before coming to rest. 3:20 Determining the magnitude of the Force of Static Friction 4:09 Understanding the “less than or equal” sign 6:08 If the “less than or equal” sign were not there Page 1 of 1. How to find the coefficient of friction on a flat surface. Watch. how to find coefficient of friction between two surfaces: coefficient of friction theory: how to find work done by friction without coefficient: static friction normal force: kinetic coefficient of friction equation: how to find the coefficient of friction in a pulley system: coefficient of friction simple definition The other block and the friction force are pulling the opposite direction, so F1-F2-Ffriction=Ftotal=ma. The other block and the friction force are pulling the opposite direction, so F1-F2-Ffriction=Ftotal=ma. Friction.
