A spherically symmetric object, with radius = 0.50 m and mass = 1.9 kg, rolls without slipping across a horizontal floor, with velocity = 0.8 m/s. It then rolls up an incline with an angle of inclination = 28o and comes to rest a distance = 3.9 m up the incline, before reversing direction and rolling back down. Find the moment of inertia of this object about an axis through its center of mass.
