An 80-kg student collides with a padded wall in the gymnasium while moving at 6.0 m/s. Because he collided with a padded wall instead of a concrete wall, the time of collision was
increased by a factor of 10. What affect does this increase in collision time have upon the
force and the impulse that he experiences? Select two answers.
1. Colliding with the padded wall will make the force 10 times greater.
2. Colliding with the padded wall will make the force 10 times smaller.

  2. Colliding with the padded wall will make the force 10 times smaller

Explanation:

Impulse is the product of force and time. Its units are those of momentum. Assuming the change in momentum (impulse) remains the same, the increase in time means the force will be decreased by the same factor.

Colliding with the padded wall will make the force 10 times smaller

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
