1. The problem statement, all variables and given/known data A uniform sphere of radius r and weight W slides along the floor due to a constant horizontal force P applied by a string. Suppose the coefficient of friction is µ. Find the height of the string above the floor h. 2. Relevant equations ƩT = 0 because there cannot be non-zero torque as the sphere must not roll, as it is sliding. T = r x F Friction = μ*W 3. The attempt at a solution ƩT = 0 = T(P) + T(Friction) = r x P + r x F(Friction) = rPsinθ + rF(Friction) = rPsinθ + rμW => -rPsinθ = rμW => sinθ = -(μW/P) I have it to the definition of the angle of the force applied, but how do I relate the angle to the height above the ground?
