After a wave passes through a medium, how does the position of a particle in that medium compare to its original position? A. The particle’s position is about the same as its original position.

B. The particle’s position moves away from its original position in the direction of the wave.

C. The particle’s position is continually vibrating around its original position.

D. The particle’s position moves away from its original position perpendicular to the direction of the wave.

The great sandini is a 60.0-kg circus performer who is shot from a cannon (actually a spring gun). you don’t find many men of his caliber, so you him design a new gun. this new gun has a very large spring with a very small mass and a force constant of 1100 n/m that he will compress with a force of 4400 n. the inside of the gun barrel is coated with teflon, so the average friction force will be only 40.0 n during the 4.00 m he moves in the barrel. at what speed will he emerge from the end of the barrel, 2.50 m above his initial rest position?
