Acat sees its his favorite human come in the door and runs toward him. the cat starts with a velocity of 4.94 m/s and slows to a velocity of 1.78 m/s in 1.25 seconds.
a) calculate the cat's average acceleration.
b) calculate the cats displacement.

Average acceleration =-2.53m/s^2

Displacement s = 4.2m

Explanation:

The answer is water molecules are split.cellular respiration and photosynthesis are complement  reactions to each other. these are reverse reactions. in cellular respiration glucose and oxygen yield water and carbon dioxide. so, when respiration begins,  glucose molecules are split. in the opposite reaction - in photosynthesis, carbon dioxide and water yield glucose and oxygen. thus,  when respiration begins, water molecules are split.
