A thin, hollow 60.0 g section of pipe of radius 15.0 cm starts rolling (from rest) down a 18.5° incline 5.40 m long.
(a) If the pipe rolls without slipping, what will be its speed at the base of the incline?
m/s
(b) What will be its total kinetic energy at the base of the incline?
J
(c) What minimum value must the coefficient of static friction have if the pipe is not to slip?
