Problem 17P

The angular speed of a propeller on a boat increases with constant acceleration from 11 rad/s to 28 rad/s in 2.4 seconds. Through what angle did the propeller turn during this time?

Solution 17P

Step 1 of 3:

A propeller’s angular speed increases with constant acceleration in 2.4 s. We are going to find the angular displacement of the propeller.

The initial angular speed ⍵0 = 11 rad/s

The final angular speed ⍵ = 28 rad/s

The time taken t = 2.4 s
