A) Find the acceleration (take free fall to be 9.8 m/s^2)
B) Find the friction force
C) Find the minimum coefficient of friction needed to prevent slipping© BrainMass Inc. brainmass.com October 10, 2019, 1:52 am ad1c9bdddf
Since the sphere doesn't slip;
torque = (moment of inertia of sphere)(angular acceleration) = (force due to friction)(radius of sphere)
Iα = (Ff)(r)
if we ...
