You are driving at 22.0 m/s when you suddenly slam on the brakes to avoid a collision. You come to a complete stop. When you stop, your acceleration is determined by your tires and the road conditions, and it is a constant -9.60 m/s^2. The skid marks you leave behind can be measured to determine your displacement. How long will our skid marks be?

Please find attached photograph for your answer.

Sorry i don’t know what to do

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.
