Hey there!
Assuming that
!["f" = y](https://tex.z-dn.net/?f=%22f%22%20%3D%20%20y%20)
So, let's solve your function, shall we?

Answer:
Step-by-step explanation:
It makes the object move faster
Answer:
4,200
Step-by-step explanation:
$60,000 divided by 3,500 is 4,200
The angular velocity is 16 radians per second
<u>Solution:</u>
The angular velocity of point is given by formula:
![w = \frac{v}{r}](https://tex.z-dn.net/?f=w%20%3D%20%5Cfrac%7Bv%7D%7Br%7D)
Where,
w is the angular velocity in radians
v is the linear velocity
r is the radius
Given that diameter of wheel is 10 feet
![radius=\frac{diameter}{2}](https://tex.z-dn.net/?f=radius%3D%5Cfrac%7Bdiameter%7D%7B2%7D)
![radius = \frac{10}{2}=5](https://tex.z-dn.net/?f=radius%20%3D%20%5Cfrac%7B10%7D%7B2%7D%3D5)
Thus radius is 5 feet
A point on the rim of a wheel moves with a velocity of 80 feet per second
Linear velocity = v = 80 feet per second
Therefore, angular velocity is given as:
![w = \frac{80}{5} = 16](https://tex.z-dn.net/?f=w%20%3D%20%5Cfrac%7B80%7D%7B5%7D%20%3D%2016)
Thus angular velocity is 16 radians per second
