Civil Engineering

Q2. A sphere of radius r and weight W is released with noinitial velocity on a (C*) degrees incline and rolls withoutslipping. Determine: (a) the minimum value of the coefficient ofstatic friction (µ) compatible with the rolling motion, (b) thevelocity (Vb) of the center G of the sphere after the sphere hasrolled (D*) meters, (c) the velocity (Vc) of G if the sphere wereto move (D*) meters down a frictionless (C*) degrees incline. (g =9.81m/s2) Report the following in the results summary table: part(a): µ = ? (10 points) part (b) Vb = ? (m/s) (10 points) part (c)Vc =? (m/s) (10 points)
