Use the formular d = v x t
d = 2m
v= 100m/s
t= d / v
= 2 / 100
= 0.02sec
Answer:
The angular acceleration is 
Explanation:
Given that,
Angular velocity, 
Angular velocity, 
Time t = 10.0 sec
We need to calculate the angular acceleration
Using formula of angular acceleration



Now, we change the angular velocity in rad/s.




Hence, The angular acceleration is 
These forces form a force pair. Use Newton's third law, and you see that the trailer pulls back at with the same force. The answer is d.
