A 2.0-kg object moving at 5.0 m/s encounters a 30-Newton restive force
over a duration of 0.10 seconds. The impulse (magnitude only) experienced
is object is approximately N-s

The impulse experienced by the object is 3 N s.

Explanation:

Impulse is also termed as change in the momentum of the object. So, it is directly proportional to the force acting on the object and the time for which the force is acting on that object.

Thus, impulse experienced by an object is the product of force acting on the object for a given time period. So, it is the sudden influence of force on the given volume.

As the force is given as 30 N and the duration or the time is given as 0.1 seconds. Then, the impulse will be product of force with duration.

Impulse = Force × ΔTime = Force × Duration

Impulse = 30 × 0.1 = 3 N s.

Thus, the impulse experienced by the object is 3 N s.
