Imagine that you are designing a small car and you want to make it as safe as possible. There are two ways that you can design the car for a collision. One is to make it so that the car will crumple up (keeping the passenger compartment rigid so they don’t get squashed!) and come to rest along with the other vehicle. The other method is to make the car very rigid so that it will bounce off of the other vehicle. Which method will be safer to use?

A. The crumple method, because the force experienced by the passengers will be less in this case.

B. The crumple method, because the car absorbs all the forces that would otherwise act on the person.

C. The rigid method, because the rigid body sends the forces back to the other car.

D. The rigid method, because the rigid body carries the impulse away from the passengers.

E. Both are equally effective.

Two loudspeakers, 5.5 m apart and facing each other, play identical sounds of the same frequency. you stand halfway between them, where there is a maximum of sound intensity. moving from this point toward one of the speakers, you encounter a minimum of sound intensity when you have moved 0.33 m . assume the speed of sound is 340 m/s.part a) what is the frequency of the sound? part b) if the frequency is then increased while you remain 0.21 m from the center, what is the first frequency for which that location will be a maximum of sound intensity? express your answer to two significant figures and include the appropriate units.
