Answer:

Explanation:

If no Energy is lost ( either as Sound energy or any other energy) the total energy of ball A equals the total energy of ball B

Therefore the Kinetic Energy of Ball B equals the Total Energy of Ball A minus the Potential Energy of Ball A

K. E = T. E - P.E

Answer:

Incomplete question:

mA = 4 kg

h point I = 5 m

mB = 2 kg

h point II = 2 m

Answer: the kinetic energy of ball B at point II is 156.8 J
