Question

A person pushes with a force of 2.00 N on a stick that is 3.00 m long directly toward the axis of an object whose moment of inertia is 4.00 kg m2 about that axis. If the object had been rotating at 5.00 rad/s, 6.00 s later its rate of rotation will be:
a. 4.00 rad/s
b. 5.00 rad/s
c. 9.00 rad/s
d. 14.00 rad/s
e. none of these.

Answer 1

option b is correct.

since force is passing through axis, its torque is zero, so angular velocity will not change.
