11. Momentum & Impulse

What is the primary role of airbags in vehicles in terms of impulse and momentum?

An object receives an impulse. Which of the following statements is true?

Which statement accurately describes $J$ (impulse) in physics?

A ball of mass $m$ is moving horizontally with speed $v$ toward a wall. It strikes the wall and rebounds in the opposite direction with the same speed $v$. What is the magnitude of the impulse delivered by the wall to the ball?

Which of the following best describes the relationship between impulse and momentum in classical mechanics?

A constant force $F_{\max }$ acts for $t$ = $0.12$ s, delivering an impulse of $9.6Ns$. What is the value of $F_{\max }$?

A $250g$ particle is subjected to a constant force of $4N$ for $3s$. What is the magnitude of the impulse delivered to the particle by the force?

A $3.0\mathrm{kg}$ particle experiences a constant force of $6.0N$ for $4.0s$. What is the impulse delivered to the particle during this time?

In a graph of $F$ (force) versus $t$ (time), what represents the impulse delivered by the force?

In the context of linear motion, how does the impulse delivered to an object relate to its change in momentum?

(III) Air in a 120-km/h wind strikes head-on the face of a building 45 m wide by 75 m high and is brought to rest. If air has a mass of 1.3 kg per cubic meter, determine the average force of the wind on the building.
