Awheel with rotational inertia i is mounted on a fixed, frictionless axle. the angular speed ω of the wheel is increased from zero to ωf in a time interval t. what is the average net torque τ on the wheel during this time interval?

In order for the bug to fly through the air a force has to push the bug forward. identify this force. how does the bug produce

Imagine that someone pushes one marble toward a motionless marble. would there still be action-reaction forces involved in the collision? how might the marbles’ motions be changed? ?

The system is released from rest with the cable taut, and the homogeneous cylinder does not slip on the rough incline. determine the angular acceleration of the cylinder and the minimum coeffi cient s of friction for which the cylinder will not slip.
