When you switch your room fan from medium to high speed, the blades accelerate at 1.2 radians per second squared for 1.5 seconds. If the initial angular speed of the fan blades is 3.0 radians per seconds, what is the final angular speed of the fan blades in radians per second?​

Answer:

4.8 rad/s

Explanation:

In image: ∆w is the final angular speed minus the initial angular speed and ∆t is the time over which the angular speed changes. You know the initial angular speed of the fan blades, so you can write

∆w= w base f -(minus) w base i ,where w base i= 3.0 rad/s.

Now, Solve the equation for acceleration for the final angular speed and plug in the known quantities to get the answer. The rest solution is in image.
