QUESTION:
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?
ANSWER:
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
