Final answer:
To find the final angular speed, we need to know the initial angular speed and the angular acceleration. Further information is needed to solve the problem.
Step-by-step explanation:
To find the final angular speed, we need to know the initial angular speed and the angular acceleration. If the initial angular speed is 0.50 rev/s, we can convert it to radians per second by multiplying it by 2π (2π rad/s = 1 rev/s). Therefore, the initial angular speed is 0.50 rev/s x 2π rad/s = 1.57 rad/s.
To find the final angular speed, we can use the equation:
final angular speed = initial angular speed + (angular acceleration x time)
Since the question does not provide the value of angular acceleration or time, we cannot determine the final angular speed without additional information.
