Problem 16P

The angular speed of a propeller on a boat increases with constant acceleration from 12 rad/s to 26 rad/s in 2.5 revolutions. What is the acceleration of the propeller?

Solution 16P

Step 1 of 2:

The angular speed of a propeller increases with constant acceleration in 2.5 revolutions. We are going to find the acceleration of the propeller.

The initial angular speed ⍵0 = 12 rad/s

The final angular speed ⍵ = 26 rad/s

The change in angular displacement Δθ = 2.5 revolutions
