momentum formula: p=mv
22kg.m/s+20kg.m/s= p
42kg.m/s=p
the momentum of both objects=42 kg.m/s

Brain, spinal cord, nerves
The brain controls thought, behavior, emotion, memory, and basic life functions. The brain is also the origin of control over body movement. The spinal cord connects the peripheral nervous system (PNS) to the brain; nerve impulses reaching the spinal cord through sensory neurons are transmitted up into the brain. Nerves primarily involve control and coordination of all parts of the body.
The nervous system interacts with every other organ system. For example the hypothalamus in the brain controls the pituitary gland and tells it when to produce hormones, this shows that the nervous system interacts with the endocrine system.
Hope this helps :)
