Is there a genius out there that can solve this mechanical maths question!?!?
For a block sliding down an inclined plane, component of gravitational force acts along the plane = mg sin a component of gravitational force acting normal to the surface of the plane = mg cos a a = angle of incline = 40 degrees m = mass of particle g = gravitational acceleration Frictional force = u * normal force, where u = coefficient of friction therefore, we have force along the surface = mg sin a – friction = mg sin a – u mg cos a Therefore, acceleration = force / mass acceleration = 3 m/s2 = g*sin(40) – u*g*cos(40) Solve this to get the value of u
