Answer:
F = 2 [N], choose option (2)
Explanation:
The principle of impulse is defined by the following expression:
Impulse = Force * Time
Force = force acting [N] or [kg*m/s^s]
Time = time during the impulse [s]
Replacing:
Impulse = 10[kg*m/s^2] * 10 [s]
Impulse = 0,1 [kg*m/s]
Now with this impulse, we can find the force for the new time.
F = Impulse/Time
F = 0.1[kg*m/s] / 0.05[s]
F = 2 [N]
