Here as we know that there is no loss of energy
so we can say that maximum kinetic energy will become gravitational potential energy at its maximum height
So here we have

here we have
v = 20 m/s
m = 8000 kg
now from above equation we have



so maximum height is 20.4 m
The answer is : D
Reasoning:
Homeostasis is the body’s balance
C. It transfer energy as heat to the surrounding air. This answer is incorrectly
