The dung beetle is known as one of the strongest animals for its size, often forming balls of dung up to 10 times their own mass and rolling them to locations where they can be buried and stored as food. a typical dung ball formed by the species k. nigroaeneus has a radius of 1.95 cm and is rolled by the beetle at 6.30 cm/s.

The angular speed of rolling ball is 3.23 rad/sec.

Explanation:

Given that,

Radius = 1.95 cm

Speed = 6.30 cm/s

Suppose, we need to find the angular speed of rolling  ball

We need to calculate the angular velocity

Using formula of angular velocity

Where, r = radius

= angular velocity

Put the value into the formula

Hence, The angular speed of rolling ball is 3.23 rad/sec.

inverse v=i*r
