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.

a) The impulse is the same in both situations

Explanation:

Impulse = Change in momentum

Impulse = m(v₂ - v₁)

The speed was brought to a stop in both cases, it doesn't matter whether it is suddenly or slowly, v₂ = 0 m/s for both cases. The initial speed is also v₁ = 2.5 m/s for both cases. Since v₂ and v₁ is the same for both cases, v₂-v₁ is also the same, hence change in momentum is the same since the mass remains unchanged.

Since impulse is concerned with change in momentum, i.e. Final momentum - initial momentum, the impulse is the same in both situations.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.

the answer is a. hope this .
