APFIVE Net Torque and Angular Acceleration
A wheel with moment of inertia 5.0 kg·m² rotates at 10 rad/s. Two forces are applied tangentially to its rim (radius 0.5 m): a 20 N force in the direction of rotation and a 30 N force opposite to rotation. What will be the wheel’s angular velocity after 2.0 seconds?
A
6.0 rad/s
B
0 rad/s
C
14.0 rad/s
D
8.0 rad/s
