To solve this problem we will apply the concepts related to the equations of linear motion and angular motion in order to find the radius. Our values are given as,

g=9.81m/s^2

Then

4g= 39.24 m/s^2

The relation between the acceleration and the angular velocity and the radius is,

a_c=\omega^2*r

The angular velocity and the lineal velocity can be related as,

v=\omega r

The acceleration and the velocity was given, then

39.24=\omega^2 r

600=\omega r \rightarrow r = \frac{600}{\omega}

Replacing at the first equation we have,

39.24 = \omega^2 (\frac{600}{\omega} )

\omega = \frac{39.24}{600}

\omega = 0.0654rad/s

Now using this expression to find the radius we have that

r = \frac{600}{\omega}

r = \frac{600}{0.0654}

r = 9174.31 \approx 9200m

Therefore the correct answer is C.

ahrayia [7]

Work is equal to the force applied times the displacement. Since you pull the wagon at constant speed this means that there is no acceleration on the wagon as it does not change speed. F=ma. Since a=0, F=0. Therefore no work has been done in this situation

A clam of mass 0.12 kg dropped by a seagull takes 3.0 s to hit the ground. [Neglect friction.]
inna [77]
This is a defective, misleading question, and should never be asked in a Physics class.

There is no such thing as the force due to the impact.

If you know how long it takes the clam to stop once it begins to hit the dirt,
then you can calculate the impulse transferred to it, and tease a force out
of that.  But the question doesn't give us the time. 

It depends on the material of the surface.  Was the clam dropped onto dirt ? 
Into a dumpster ?  Onto grass ?  Concrete ?  Styrofoam ?  Mud ?  The answer
is different in each case, and we still need to know the short length of time
AFTER it first encountered whatever surface brought it to rest.

I would kick this question back to the Physics teacher.  It's meaningless,
and the longer you try to work on it, the more nonsense you'll plant into
your head that'll need to be dug out later.
