Question 1
A thin uniform ring (hoop) and a solid uniform disk both have the exact same total mass M and outer radius R. How do their moments of inertia about a central axis perpendicular to their plane compare?
Correct Answer:
The ring has twice the moment of inertia of the disk.
Question 2
A heavy flywheel starts from rest and accelerates with a constant angular acceleration of 4.0 rad s^-2. What total angular displacement does the flywheel undergo during the first 5.0 s of motion?
Correct Answer:
50 rad
Question 3
An object executing simple harmonic motion (SHM) has an amplitude of 0.20 m and a time period of 2.0 s. What is the maximum magnitude of acceleration experienced by the object?
Correct Answer:
1.97 m s^-2
Question 4
A figure skater spinning on frictionless ice pulls her arms inwards, reducing her moment of inertia to half its initial value (I_f = 0.5 * I_i). What happens to her rotational kinetic energy?
Correct Answer:
It doubles (E_k,f = 2 * E_k,i).
Question 5
A satellite moves in a stable circular orbit around Earth at an orbital distance r from Earth's center. If the satellite's orbital radius is quadrupled to 4r, how does its orbital speed v change?
Correct Answer:
The orbital speed is halved (v_new = 0.5 * v).
