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?

Angular velocity of Dalnita,

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 :

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

resonant frequency

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
