With the aid of a string, a gyroscope is accelerated from rest to 32 rad/s in 0.40 s. (a) What is its angular acceleration in rad/s2 ? (b) How many revolutions does it go through in the process?

Step-by-step solution Step 1 of 7 Equation to find the angular velocity is, Here is the final angular velocity, is the initial angular velocity, is the angular acceleration, is the time taken. Step 2 of 7 (a) Use the above formula, Step 3 of 7 Substitute 32 rad/s for , 0 rad/s for and 0.40 s for . Therefore, Step 4 of 7 Therefore, the angular acceleration of the gyroscope is .
