If the impulse applied to an object is 34 Ns when a force Facts on it for 3 s, then the force acting on it is which of the following?

Force = 11.33 Newton

Explanation:

Given the following data;

Impulse = 34 Ns

Time = 3 seconds

To find the force acting on the object;

Impulse = force * time

Substituting into the formula, we have;

34 = force * 3

Force = 34/3

Force = 11.33 Newton

Note: the impulse of an object is equal to the change in momentum experienced by the object.
