. Which of the following is a vector describing how fast an object moves over a long time interval?. . average speed. instantane
2 answers:
By definition we have to:
The average velocity is that velocity in a given time interval. It is calculated by dividing the displacement by the elapsed time, according to the following formula:
We must remember that the average velocity is a vector. Therefore, it has magnitude and direction.

Answer:
The angular velocity is 15.37 rad/s
Solution:
As per the question:
Horizontal distance, x = 30.1 m
Distance of the ball from the rotation axis is its radius, R = 1.15 m
Now,
To calculate the angular velocity:
Linear velocity, v =
v =
v =
v =
Now,
The angular velocity can be calculated as:
Thus
