WebThe force of friction here, completely offsetting the parallel force of gravity parallel to the surface, is 49 newtons. And the normal force here, the force of contact between these two things, this block and this wedge, is 49 square roots of 3 newtons. So we get 1 over the square root of 3. WebFeb 13, 2024 · There are two easy methods of estimating the coefficient of friction: by measuring the angle of movement and using a force gauge. The coefficient of friction is equal to tan(θ), where θ is the angle from the …

WebApr 10, 2024 · acceleration due to gravity under angle ->Fg=mgsin60, Normal force -> Fn=mgcos60, Ffriction = mi (coefficient of friction)*Fn. So basically I need to find the coefficient of friction given the listed information. What bothers me is that I am getting two different accelerations for two different approaches. When I calculate acceleration using … WebOnce there is motion, friction is less and the coefficient of kinetic friction might be 0.30, so that a force of only fk = μkN = (0.30)(980N) = 290N keeps it moving at a constant speed. If the floor is lubricated, both coefficients are considerably less … cinnamon johnson beauty pageant
