Question

Identical cannonballs are fired with the same force, one each from four cannons having respective bore lengths of 1.0 meter, 2.0 meters, 2.5 meters and 3.0 meters. Which cannon will have the minimum impulse on the ball if the force acting on the ball increases with the length of the bore?

Answer 1

I think its options 2 idk man

Answer 2

1 meter

Step-by-step explanation:

• Think of it as distance smaller distance means less momentum and longer distance requires big momentum.
• Therefore smallest bore length i.e. 1 meter will have minimum impulse.
