Suppose a 65 kg person stands at the edge of a 6.5 m diameter merry-go-round turntable that is mounted on frictionless bearings
ozzi

Answer:

0.3165\ \text{rad/s}

Explanation:

m = Mass of person = 65 kg

d = Diameter of round table = 6.5 m

r = Radius = \dfrac{d}{2}=3.25\ \text{m}

v = Velocity of person running = 3.8 m/s

I_t = Moment of inertia of turntable = 1850\ \text{kg m}^2

Moment of inertia of the system is

I=I_t+mr^2\\\Rightarrow I=1850+65\times 3.25^2\\\Rightarrow I=2536.5625\ \text{kg m}^2

As the angular momentum of the system is conserved we have

L_i=L_f\\\Rightarrow mvr=I\omega_f\\\Rightarrow \omega_f=\dfrac{mvr}{I}\\\Rightarrow \omega_f=\dfrac{65\times 3.8\times 3.25}{2536.5625}\\\Rightarrow \omega_f=0.3165\ \text{rad/s}

The angular velocity of the turntable is 0.3165\ \text{rad/s}.

The earth exerts a force of 1.00 newtons on an object in free fall. what is the objects mass?
ICE Princess25 [194]
On or near the surface of the Earth, 1 newton is the weight of about 102 grams of mass.

Note that the gravitational force between the object and the Earth is always the
same.  It doesn't matter whether the object is falling, flying, floating, fluttering,
rising, sinking, rolling, sliding, or just laying there. It doesn't change.

The table lists the speed of light in four different materials at the same temperature. Through which material would light trave
bija089 [108]
I would say diamond because of how durable of a material it is. The light also travels the slowest for m/s.
