Magnitude and Direction of Friction Force on Block
WebMar 2, 2009 · Magnitude of F = W/change in X, but no X is given, just Y. I know F= mu/N and I found normal force to be [51.1 kg*9.8 m/s^2 cos (45)]=354 N I am stuck there and cannot think of a way to calculate mu. You know how fast he was going frictionless. Now they tell you how fast he was going under less than ideal conditions. i.e with friction. WebHow to determine magnitude of friction force Coefficient of friction ( μ \mu μ mu ): this describes the roughness between two surfaces. A high coefficient of... Normal force ( F N F_N F N F, start subscript, N, end subscript ): squeezing surfaces together more tightly … WebThus, the magnitude of centripetal force F c is. F c = m a c. By substituting the expressions for centripetal acceleration a c ( a c = v 2 r; a c = r ω 2), we get two expressions for the … chandler perry mit
