Answer:
The ratio of kinetic energies of 5 kg object to 20 kg object is 1:1.
Explanation:
Kinetic energy is defined as energy possessed by an object due to its motion.It is calculated by:
Kinetic energy of the 5 kg object.
Mass of object,m = 5 kg
Velocity of an object = v
Kinetic energy of the 20 kg object.
Mass of object,m' = 20 kg
Velocity of an object = v'
The ratio of the kinetic energy of the 5 kilogram object to the kinetic energy of the 20-kilogram object:
Given that, v = 2v'
The ratio of kinetic energies of 5 kg object to 20 kg object is 1:1.

Answer:
The minimum diameter of the stick to bear the normal stress as 100 psi is 0.1785 in.
Explanation:
Taking moment along point A
Also normal stress is given as 100 psi
Now
The minimum diameter of the stick to bear the normal stress as 100 psi is 0.1785 in.
