Planar Kinematics of a Rigid Body (PKRB)
12.

The sphere starts from rest at = 0 and rotates with an angular acceleration of = (4) rad/s2, where is measured in radians. Determine the magnitudes of the velocity and acceleration of point P on the sphere at the instant = 6 rad.

vP = 96.0 in./s, aP = 1168 in./s2
vP = 135.8 in./s, aP = 2310 in./s2
vP = 83.1 in./s, aP = 1011 in./s2
vP = 117.6 in./s, aP = 2000 in./s2
