The Gravitron is a ride that rotates around a central axis until it reaches a certain velocity and the riders are pinned to the

walls. Once this occurs, the floor is lowered until the riders are suspended above the floor. The Gravitron has a radius of 3.00 meters and reaches a speed of 15.0 m/s. Dalnita has a mass of 55.0 kg. What is her angular velocity in radians per second?

Sounds like you've been given some unnecessary information. 
<span>The linear velocity "v" and angular velocity "w" of something in circular motion of radius "R" are related as; </span>

<span>v = Rw </span>

<span>You are given v= 15 m/s and R = 3 m , so just solve for "w".</span>

Answer:

Angular velocity of Dalnita, \omega=5\ rad/s

Explanation:

It is given that,

The radius of Gravitron, r = 3 m

Speed of gravitron, v = 15 m/s

Dalnita's mass, m = 55 kg

We need to find her angular velocity. The relationship between the angular velocity and linear speed is as follows :

v=r\times \omega

\omega=\dfrac{v}{r}

\omega=\dfrac{15\ m/s}{3\ m}

\omega=5\ rad/s

So, her angular speed is 5 radian per second. Hence, this is the required solution.

Answer:

-10C= Solid

10C= Liquid

50C= Liquid

90C= Liquid

110C= Gas

120C= Gas

Explanation:

Below 0 degree C (Celsius), water is frozen means it is in the form of ice. After 0 degree, once we keep it in room temperature, the ice starts becoming liquid (water), and once we heat water, after 100 degree C (Celsius) water starts boiling and thus starts entering gaseous state.
