Have you tried to look this up on Quizlet. I just had a similar question on one on my quizzes & the whole test was on Quizlet
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
.
Trees. Every time the wind blows there is a wave of motion which is movement
