    Clyde will provide greater impulse

    Explanation:

    We have given that Al exerts a force of 200 N for 5 sec

    We know that impulse is given by, impulse = force * time = 200*5 = 1000 N-s

    Bill exerts a force of 500 N for 2 sec

    So impulse = 500*2 = 1000 N-s

    Now the force exerted by Clyde 300 N for 4 sec

    So impulse = 300*4 = 1200 N-s

    From above calculation we can see that Clyde provide greater impulse than any other
