Reference no: EM13647884

A hollow sphere of radius 0.50 m, withrotational inertia I = 0.026 kgm2 about a line through its center of mass, rollswithout slipping up a surface inclined at 30° to the horizontal. At a certain initialposition, the sphere's total kinetic energy is 100 J.

(a) How much of this initial kinetic energy is rotational?

(b) What is the speed of the center of mass of the sphere at theinitial position?

m/s

(d) What is the speed of its center of mass now?

m/s
