Suppose the ring rotates once every 4.30 ss . If a rider's mass is 58.0 kgkg , with how much force does the ring push on her at the top of the ride? Express your answer with the appropriate units.

Respuesta :

Answer:

422.36 N

Explanation:

given,

time of rotation = 4.30 s

T = 4.30 s

Assuming the diameter of the ring equal to 16 m

radius, R = 8 m

[tex]v = \dfrac{2\pi R}{T}[/tex]

[tex]v = \dfrac{2\pi\times 8}{4.30}[/tex]

  v = 11.69 m/s

now, Force does the ring push on her at the top

[tex]- N - m g = \dfrac{-mv^2}{R}[/tex]

[tex] N + m g = \dfrac{mv^2}{R}[/tex]

[tex] N = \dfrac{mv^2}{R}- m g[/tex]

[tex] N = m(\dfrac{v^2}{R}- g)[/tex]

[tex] N = 58\times (\dfrac{11.69^2}{8}- 9.8)[/tex]

N = 422.36 N

The force exerted by the ring to push her is equal to 422.36 N.

The force does the ring push on her at the top of the ride will be [tex]N=422.36\ Newton[/tex]

What will be the force does the ring push on her at the top of the ride?

It is Given that

Time rotation  T= 4.30 s

Mass m= 58 kg

Now the Velocity will be calculated as

[tex]V=\dfrac{2\pi r}{T} =\dfrac{2\pi 8}{4.30} =11.69 \frac{m}{s}[/tex]

Now by balancing the forces

[tex]N=\dfrac{mv^2}{R} -mg[/tex]

[tex]N=m(\dfrac{v^2}{R} -g)[/tex]

[tex]N=58\times (\dfrac{11.69^2}{8} -9.8)[/tex]

[tex]N=422.36 \ Newton[/tex]

Thus the force does the ring push on her at the top of the ride will be [tex]N=422.36\ Newton[/tex]
