A hollow spherical shell with mass 1.65 rolls without slipping down a slope that makes an angle of 40.0 with the horizontal.
1) Find the magnitude of the acceleration of the center of mass of the spherical shell. Take the free-fall acceleration to be = 9.80 . m/s^2
2) Find the magnitude of the frictional force acting on the spherical shell. Take the free-fall acceleration to be = 9.80 .m/s^2/
