What role does the somatic nervous system play?
kodGreya [7K]

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.
  • The somatic nervous system controls the voluntary actions of movement in the body.
  • It coordinates the reflex arc.

Una niña está empujando un baúl. El PESO del baúl es de 230 N y el roce es de 50 N, la niña sólo logra ejercer una fuerza de 30
Gre4nikov [31]

Answer:

Su padre necesita aplicar una fuerza de 20 newtons en la misma dirección que la fuerza aplicada por su hija.

Explanation:

Asúmase que el baúl se mueve en una superficie horizontal. La fuerza de rozamiento dada por el problema es la fuerza de rozamiento estático máximo, se requiere una fuerza externa antiparalela a la fuerza de rozamiento estático máximo para que el baúl se empiece a mover. La ecuación de equilibrio de fuerzas horizontales sobre el baúl es:

\Sigma F = P - f = 0

Donde:

P - Fuerza externa aplicada sobre el baúl, medida en newtons.

f - Fuerza de rozamiento estático máximo, medida en newtons.

Se despeja la fuerza externa:

P = f

Si f = 50\,N, entonces:

P = 50\,N

Si la niña solo logra ejercer una fuerza de 30 newtons, su padre necesita aplicar una fuerza de 20 newtons paralela a aquella fuerza.

A typical jetliner lands at a speed of 146 mi/h and decelerates at the rate of (10.4 mi/h)/s. If the jetliner travels at a const
zzz [600]

jetliner is moving with speed 146 mi/h

now we will have

v= 146 \frac{1609 m}{3600 s}

v = 65.25 m/s

now if it moves with this speed for 1.5 s

so the displacement for above time

d_1 = 1.5(65.25) = 97.9 m

now the deceleration of jet is given as

a = - 10.4 mi/h/s

a = -(10.4)(\frac{1609 m}{3600 s})\frac{1}{s}

a = - 4.65 m/s^2

now by kinematics

v_f^2 - v_i^2 = 2ad

0 - 65.25^2 = 2(-4.65)(d_2)

d_2 = 457.8 m

so total displacement is given as

d = d_1 + d_2

d = 97.9 + 457.8 = 555.7 m

so displacement will be 555.7 m
