A spherically symmetric object, with radius R = 0.700 m and mass M = 1.90 kg, rolls without slipping across a horizontal floor, with velocity V = 1.200 m/s. It then rolls up an incline with an angle of inclination θ = 40.0 deg and comes to rest a distance d = 0.177 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.
I have no idea where to start
