The answer is D, the brain actually stops growing around age 18
Answer:
9.21954 m/s
54 m/s²
Angle is zero
Explanation:
r = Radius of arm = 1.5 m
= Angular velocity = 6 rad/s
The horizontal component of speed is given by

The vertical component of speed is given by

The resultant of the two components will give us the velocity of hammer with respect to the ground

The velocity of hammer relative to the ground is 9.21954 m/s
Acceleration in the vertical component is zero
Net acceleration is given by

Net acceleration is 54 m/s²
As the acceleration is towards the center the angle is zero.
Explanation:
The somatic nervous system coordinates the voluntary control of movement in the body system.
The nervous system is made up of the central nervous system and peripheral nervous system.
The peripheral nervous system is made up of the nerves that branches into the body from the spinal cord.
- It consist of the somatic nervous system and the autonomous nervous system.
