The assembly is upright, but we nudge it so that it rotates around a horizontal axis in the plane of the rod and hoop, through the lower end of the rod. Assuming that the energy given to the assembly in the nudge is negligible what is the assembly's angular speed about the rotation axis when it passes through the upside-down (inverted) orientation? 16 41 28 067 046 13 41 63 71 Hoop Rod Rotation dy axis Number Units the tolerance is +/-2% SHOW HINT GO TUTORIAL LINK TO TEXT LINK TO SAMPLE PROBLEM LINK TO SAMPLE PROBLEM LINK TO SAMPLE PROBLEM LINK TO SAMPLE PROBLEM VIDEO MINI-LECTURE Question Attempts: Unlimited SAVE FOR LATER SUBMIT ANSWER SUBMIT ANSWER edu gen.wileyplus.com/edugen/shared/assignment/test/agli st.uni#N 1005 B I'm Cortana.

let m = 0.1 kg
m = 0.1 kg
Apply conservaion of energy
gain in kinetic energy = loss of potentail eneegy
0.5*I*w^2 = m*g*6*R + m*g*2*R
0.5*(m*L^2/3 + m*R^2 + m*(L+R)^2)*w^2 = 8*m*g*R
0.5*(L^2/3 + R^2 + (2*R+R)^2)*w^2 = 8*g*R
0.5*((2*R)^2/3 + R^2 + (2*R+R)^2)*w^2 = 8*g*R
0.5*(4*R^2/3 + R^2 + 9*R^2)*w^2 = 8*g*R
w = sqrt(16*g*R/(4*R^2/3 + R^2 + 9*R^2))
= sqrt(16*9.8*0.16/(4*0.16^2/3 + 0.16^2 + 9*0.16^2))
= 9.3 rad/s
