A2 kg ball of putty moving to the right at 3m/s has a head-on inelastic collision with a 2 kg ball of putty at rest. what is the final magnitude and direction of the velocity of the stuck together balls after the collision?

My answer is opptionc, just check with anyone else

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.
