In two different experiments, an object of mass 5 kg moving with a speed of 25 ms–1 hits two different walls and comes to rest within (i) 3 second, (ii) 5 seconds, respectively.
Choose the correct option out of the following:
1
Impulse and average force acting on the object will be same for both the cases.
2
Impulse will be same for both the cases but the average force will be different.
3
Average force will be same for both the cases but the impulse will be different.
4
Average force and impulse will be different for both the cases.
