Answer:
Speed of 0.08 kg mass when it will reach to the bottom position is 1.94 m/s
Explanation:
When rod is released from rest then due to unbalanced torque about the hinge the system will rotate
Now moment of inertia of the system is given as

now we have



now we have

so we have


now by energy conservation we can say work done by gravity must be equal to change in kinetic energy
so we have



Now speed of 0.08 kg mass when it reaches to bottom point is given as



Answer:
it depends on the weight's ratio

No, Alec has not.
The force due to gravity is the same on all objects, regardless of shape and size. The acceleration caused by this force is 9.81 m/s². So if there are two identical pieces of paper, both will experience an equal force of gravity.
The difference in the papers' flight paths is due to the greater air resistance that the flat paper experiences. If the same experiment were to be repeated in a vacuum chamber, both of the pieces of paper would fall at the same rate
