In a lab environment, you are investigating the impulse of a force exerted on a brick when the brick's speed is reduced from 2.5 m/s to a complete stop. first, you allow the brick to slam into a secured piece of wood, bringing the brick to a sudden stop. second, you allow the brick to plow into a large slab of gelatin so that the brick comes to a gradual halt. in which situation is there a greater impulse of the force on the brick?
a. the impulse is the same in both situations.
b. there is a greater impulse of the force on the brick from the gelatin.
c. not enough information is given to determine the answer.
d. there is a greater impulse of the force on the brick from the wall.
