APFIVE Angular Impulse and Angular Momentum
Two identical wheels, A and B, are initially at rest. A net torque of 5 N·m acts on wheel A for 3 s, and a net torque of 15 N·m acts on wheel B for 1 s. How do the magnitudes of the final angular momenta of the two wheels compare?
A
Wheel A has three times the angular momentum of wheel B
B
Cannot be determined without knowing the moments of inertia
C
Both wheels have the same angular momentum magnitude
D
Wheel B has three times the angular momentum of wheel A
