Answer to Problem 5STP
B.
Explanation of Solution
Given:
The mass of the hoop is
The force exerted tangentially to the hoop,
The radius of the hoop is,
Formula used:
The torque can be obtained by:
Where, F is the applied force, r is the distance of the point of application of force from the axis of rotation, and
The
Where,
Calculation:
The moment of inertia of hoop is
Then, the angular acceleration of the hoop can be written as,
Using given values in above,
Conclusion:
Thus, the angular acceleration of the hoop is
