A hollow, spherical shell with mass 1.55 kg rolls without slipping down a slope angled at 39.0.
PART A) Find the acceleration. Take the free fall acceleration to be g = 9.80m/s^2
PART B) Find the friction force. Take the free fall acceleration to be g = 9.80m/s^2
PART C) Find the minimum coefficient of friction needed to prevent slipping.
