The most dense thing inside the column is the little star. It's pink, and it's resting on the bottom of the cylinder.

The red part under the star is the solid base that the cylinder is standing in. It's probably wood or plastic, it's not free to move, and it's not involved in the experiment.

A 200kg ball on the end of string is swung in horizontal circle with radius of 0.5m . The ball makes revolution every 2second th
kondaur [170]

The speed of the ball is 1.57 m/s

Explanation:

We start by calculating the angular speed of the ball, which is given by

\omega = \frac{2\pi}{T}

where

T is the period of revolution

For the ball in this problem,

T = 2 s

(since the ball makes 1 revolution every 2 seconds)

So, the angular speed is

\omega = \frac{2\pi}{T}=\frac{2\pi}{2}=\pi rad/s

Now we can calculate the speed of the ball by using

v=\omega r

where

r = 0.5 m is the radius of the circular path

Substituting,

v=(\pi)(0.5) = 1.57 m/s
