For this problem,

For part(a) the solution is,

However, how did they know that the max speed is reached in the vertical position?

For part (d) the solution is,

However, I thought the solution would be because there is net gravitational torque in clockwise direction (torque due to small mass – torque due big mass) then angular momentum is not conserved.

I don’t understand why they talk only about the lever arm of the 60 kg mass, as there is also a lever arm for the smaller mass. I agree thought about their statement that the lever arm due to the masses on each end changes as the war-wolf rotates.

Many thanks!
