What angular acceleration is necessary to increase the angular speed of a fan blade from 8.5 rads per second to 15.4 rads per second in 5.2 seconds?

Wf - Wi = a*t, where Wi and Wf are the initial and final angular velocities, respectively, a is the angular acceleration, and t is time.
So, a*t = 15.4 rad/s - 8.5 rad/s = 6.9 rad/s,
thus a = 6.9 rad/s / 5.2 s = 1.3 rad/s2.

''How do calculate velocity?
To calculate velocity using acceleration, start by multiplying the acceleration by the change in time. For example, if the acceleration is 10 m/s2 and the change in time is 5 seconds, then there is a 50 m/s increase in velocity. Then, add the initial velocity to the increase in velocity.
A 2.8kg 40cm diameter disk is spinning at 260 rpm How much friction force must the brake apply to the rim to bring the disk to halt in 2.0s The answer should be in Newtons?
Torque is equal to friction force (F) * radius (r). Torque is also equal to moment of inertia (I) * Angular acceleration (a). Angular acceleration is equal to rotational velocity * 2Pi/time, which is 2 seconds. So, F = IRa/r, or 45.63 Newtons
A skydiver steps from a helicopter and falls for 5 seconds before reaching her terminal velocity During this 5 second interval her acceleration will?
increase- your speed will increase until terminal velocity is reached. From there it will stay constant.
A car accelerates from a standstill to 60 kmhr in 10 seconds What is its acceleration?
A car accelerates from a standstill to 60km/hr in 10.0 seconds what is its acceleration
If a car goes in 6.8 seconds how do you figure out the acceleration?
Acceleration= distance / velocity squared
What is the angular velocity of the wheel before braking began if the wheel rotates through 6 radians in 2 seconds as it is uniformly brought to rest?
It was 6 radians per second. Angular acceleration = -3 radians per second2 Initial angular velocity = 6 radians per second. Final angular velocity = zero. Average angular velocity = 3 radians per second. Angular displacement in 2 seconds = 3 x 2 = 6 radians.
A car accelerates to pass a truck going from 20miles per second to 29miles per second in 3 seconds what was the acceleration?
So acceleration is an increase of speed every second. The increase of speed was 9miles/sec and this was over 3 seconds. Therefore there was an acceleration of 3 miles/second every second i.e. 3m/s2

What is the unit of measurement used for reading lines of longitude and latitude?
You would use angular degrees or angular degrees plus minutes and seconds.
How do you convert radians per seconds into degrees?
You cannot. Radians per second is a measure of angular speed whereas degrees are an angular measure.
What is the acceleration experienced by a car that takes 10 seconds to reach 27 meters per seconds from rest?
velocity = acceleration x time 27 = acceleration x 10 acceleration = 2.7 m/sec/sec
