Question

total energy of a body at rest at a height h from zero level is 80 j. what is the kinetic energy as it falls through a height h/2​

Answer 1

Answer:

total energy = 80J

the kinetic energy will be 40J as same as potential energy because at the middle of height

potential and kinetic energy divides in two equal magnitude

if correct then inform me

Answer 2
