5 question velocity help? will medal and fan
1. a lightening bug flies at a velocity of 0.25 m/s due east tword another lightening bug seen off in the distance. A light easterly breeze blows on the bug at a velocity of 0.25 m/s. What is the resultant velocity of the lightening bug? A. 0.00 m/s B. 0.25 m/s east C. 0.25 m/s west d. 0.5 m/s east
i got b? dont now how i did but i did lol
oh. do you know how? im not doing so well in physics lol
my teacher wont help because she never reads her emails lol
@SmokeyRiver
Remember an "Easterly" wind is coming from the East. That is the convention of reporting wind direction. It is not blowing towards the East, but to the West.
Wind direction is reported from the direction it originates. http://en.wikipedia.org/wiki/Wind_direction
Based on that fact, and with the earth as a frame of reference, the little fire-fly isn't making very much progress.
@radar good point.. i better delete my embarrassing comment.. before she reads and gets the wrong instinct lol!!!
I'm still hung up with the definition of velocity, I was thinking of "speed with direction" but then again what about the frame of reference, in this case I would say considering both earth (groundspeed) and the atmoshpere (airspeed) it is zero what you think @Mashy
yea its zero.. poor bug.. is gonna be stuck at that same point and when its not explicitly mentioned we will always assume its with respect to the ground
Thanks for your input.
The answer is A. 0 cx
