A hollow spherical shell having mass 1.75 kg rolls devoid of slipping down a slope which forms an angle of 40.0 with the horizontal.
i) Determine the magnitude of the acceleration a_cm of the center of mass of the spherical shell.
Obtain the free-fall acceleration to be g = 9.80 m/s^2.
ii) Determine the magnitude of the frictional force acting on the spherical shell.
Obtain the free-fall acceleration to be g = 9.80 m/s^2.
