19. Galileo falls out of his chair onto the floor, which is a height of .5 m. His mass is 91kg.

     

      a) Using conservation of energy, calculate his final velocity at the floor level.

 

      b) If he only has kinetic energy, calculate the power generated if he fell to the floor in .002 seconds.
