WebTo get the pallet started, the driver must push it with a force equal to the maximum static friction. P = fs = µ sN = µ smg P = (0.28) (600 kg) (9.8 m/s2) P = 1646 N Once the pallet starts moving, the coefficient of friction drops from its static value to its kinetic value. fk = µ kN = µ kmg fk = (0.17) (600 kg) (9.8 m/s2) fk = 1000 N WebAug 15, 2024 · If the wheels continue to roll you use the coefficient of static friction. Generally rolling resistance can be ignored. You can calculate the magnitude of the deceleration from Newtons second law. a = F m = μ m g m = μ g. And finally you can calculate the stopping time from. d = a t 2 2.

How to Calculate the Coefficient of Friction Sciencing
WebDec 8, 2024 · The formula for the force of friction states: F=\mu N F = μN For the example, consider a wood block of 2-kg mass on a wooden table, being pushed from stationary. In … WebFeb 1, 2007 · Sled question. I have a physics midterm tonite and i was trying some of the practice tests and i got stuck on this question, ur help would be greatly appreciated :) 1. The problem: A sled is traveling at 4.00m/s along a horizontal stretch of snow. The coefficeint of kinetic friction is Uk=0.05 and the coefficient of static friction Us=0.07. WebStatic friction is given by the formula: = 90 N. Therefore, the static friction will be 90 N. Q.2: A person is pushing a toy car of mass 4 kg which was at rest position on the floor. If 100 N is the value of the static frictional force, then determine the friction coefficient? Answer: Known values are as, Mass, m = 4 kg, Static frictional force, dauntless by marcus follin
