Answer:
The angular velocity at the beginning of the interval is 
.
Explanation:
Given that,
Angular acceleration 
Angular displacement 
Angular velocity 
We need to calculate the angular velocity at the beginning
Using formula of angular velocity
Where, 
= angular acceleration
= angular velocity
Put the value into the formula
Hence, The angular velocity at the beginning of the interval is .
Because of internal friction between layers of mud particles called viscosity. When you walk, your foot exerts a force on the mud; and according to Newton, the mud also (is supposed to) exert an equal opposite force, which leading to an equal net resultant force in your direction, propelling you forward.
