A wheel, initially at rest, has a moment of inertia of 2 kg-m 2. If a torque of 30 N-m is applied on the wheel for 10 seconds, how far will the wheel have turned? 750 rad. 1500 rad. 3000 rad. 6000 rad. a) A bucket filled with water has a mass of 23 kg and is attached to a rope, which in turn is wound around a 5 cm radius cylinder at the top of a well. What torque does the weight of the water and bucket produce on the cylinder? ( g = 9.81 m/s 2) 33.7 N-m 17.0 N-m 11.3 N-m 22.6 N-m b) A 40 kg boy is standing on the edge of a stationary 30-kg platform that is free to rotate without friction. The boy tries to walk around the platform in a counterclockwise direction. As he does, the platform doesn't rotate. the platform rotates in a clockwise direction just fast enough so that the boy remains stationary relative to the ground. the platform rotates in a clockwise direction while the boy goes around in a counterclockwise direction relative to the ground. both go around with equal angular velocities but in opposite directions.

a)
A bucket filled with water has a mass of 23 kg and is attached to a rope, which in turn is wound around a 5 cm radius cylinder at the top of a well. What torque does the weight of the water and bucket produce on the cylinder? ( g = 9.81 m/s 2)
33.7 N-m
17.0 N-m
11.3 N-m
22.6 N-m
b)
A 40 kg boy is standing on the edge of a stationary 30-kg platform that is free to rotate without friction. The boy tries to walk around the platform in a counterclockwise direction. As he does,
the platform doesn't rotate.
the platform rotates in a clockwise direction just fast enough so that the boy remains stationary relative to the ground.
the platform rotates in a clockwise direction while the boy goes around in a counterclockwise direction relative to the ground.
both go around with equal angular velocities but in opposite directions.
Definition Definition Rate of change of angular displacement. Angular velocity indicates how fast an object is rotating. It is a vector quantity and has both magnitude and direction. The magnitude of angular velocity is represented by the length of the vector and the direction of angular velocity is represented by the right-hand thumb rule. It is generally represented by ω.
