400x6=2400 This is how a find a product
The angular velocity is 16 radians per second
<u>Solution:</u>
The angular velocity of point is given by formula:

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


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:

Thus angular velocity is 16 radians per second
Well its a pretty strong wind the answer is 75 mph
First you find out the distance without the wind which is 4x525 or 2,100
Now subtract 1800 from that and you get 300
But you’re still not done because 300 is the number of miles effected by the wind in the whole flight of 4 hours.
So just divide it by 4 and you get 75. So the wind is a 75 mph wind.
Brainliest my answer if it helps you out?
