19. A stone with a mass of 0.5 kg falls from a
cliff. The stone was initially at rest when it began
falling. Calculate the height from which the stone
must fall in order for the kinetic energy of the
stone to be 200 J just before it hits the ground. (g
= 9.81 m/s?). Round your answer to two decimals
and show the correct units of measure.
