Correct answer: B. Impulse will be same for both the cases but the average force will be different.

Impulse = Change in momentum I = Therefore, in both the cases the impulse is same. Average force is defined as, F _ avg = ( )/( ) Since the time in the two cases is different, the average force will be different.
