Q1; Consider a hollow spherical shell that spins freely on an axis through its center. The sphere has mass m = 13.1 k g and radius r = 3.52 m . Find the force (in N ) that must be applied tangentially to the surface at its equator for the sphere's angular acceleration to be ? = 7.62 r a d / s 2 . Consider a hollow spherical shell that spins freely on an axis through its center. The sphere has mass m = 13.1 k g and radius r = 3.52 m . Find the force (in N ) that must be applied tangentially to the surface at its equator for the sphere's angular acceleration to be ? = 7.62 r a d / s 2 .

Q2: Find the moment of inertia (in kg?m2) of a solid sphere of mass m=37.1 kg, radius r=1.50 m.

Q3: Masses are distributed in the x,y-plane as follows:

8.75 kg at (2.48,?5.66) m

8.74 kg at (5.80,?3.49) m

2.03 kg at (?4.82,?4.44) m

What is the y-coordinate of the center of gravity of this system of masses?
