Question: Consider a sphere with mass m sliding, from zero initial velocity (position A), through a trajectory (in the vertical plane), passing through B, contained into the circumference of radius R with a velocity of modulus V, as the figure indicates.The friction coefficient between the particle and the trajectory is μc. The modulus of the friction force on the sphere at the position B is equal to? a) μc.M.gb) μc.M.gsenθc) μc.M.gcosθd) μc.M.( v² + Rgcosθ) / Re) μc.v².gsenθ / R Im not knowing how to set up the situation properly, so Im asking you guys. Thanks.
