A thin, hollow 0.545 kg section of pipe of radius 10.0 cm startsrolling (from rest) down a 17.5 degree incline 5.60 m long.
(a) if the pipe rolls without slipping, what will be its speed atthe base of the incline?
(b) What will be its total kinetic energy at the base of theincline?
(c) What minimum value must the coefficient of static friction haveif the pipe is not to slip?
