question 68

Multiple Choice

A spherically symmetric object with mass m = 0.2 kg and radius r = 10 cm,rolls without slipping on a horizontal surface with speed 1 m/s.It then rolls up an incline that is at an angle 30 ^$\circ$ with the horizon and comes to rest at a distance of 0.6 m along the incline.What is the moment of inertia of the object about an axis through the center of mass?

• A)1.0 \(\times\) 10^-4 kg · m²/s
• B)2.0 \(\times\) 10^-3 kg · m²/s
• C)9.8 \(\times\) 10^-3 kg · m²/s
• D)1.2 \(\times\) 10^-2 kg · m²/s
• E)8.0 \(\times\) 10^-4 kg · m²/s
