An archer standing on a cliff 48 m above the level field below shoots an arrow at an angle of 30 degrees above horizontal with a speed of 80 m/s. Calculate the duration the arrow is in the air. And can you sketch for me to view?

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
