when a fly flies (say30 kmph)within a flying jet flies 1000 kmph,what is the actual speed of fly ?

Question

when a fly flies (say30 kmph) within a jet along the direction of jet travelling, the jet travels in speed of 1000 kmph what is the actual speed of fly (have u ever saw fly flies in a bus).remember that fly wont have any physical contact with jet.

explain how?

Answer 1

The physical contact with the jet will make no difference.

And measuring speed actually depends on the frame of reference you choose.

If you measure speed from another insect flying right besides it, it would be 0kmph.
If you measure speed from the jet, it would be 30kmph.
If you measure speed from the gound, it would be 1030kmph.
If you measure speed from a stationary space satelite, assuming the jet is moving in the equator towards the east, the speed would be aproximately 168,030kmph.
If you measure it from the sun, assuming the jet is moving in the equator towards the east, and it is midnight(jet would be moving in the same direction as the earth) the speed would be about 1,072,968,030kmph.
If you measure the speed from Uranus... nah, nobody wants to hear about that.

No seriously, speed is just a number... Its like saying, im 7 years older than some guy. With "some guy" being your frame of reference....

Answer 2

he will need to have contact during acceleration or he'll end up in the back of the plane against the wall. like if you slam on the gas in your car you'll be pushed backwards or you can feel the acceleration of the plane yourself and it's pretty strong. once he is traveling at 1000 mph with the plane then he can exert whatever strength he has to fly to his personal top speed (+30kmph) forward.

you're on a train, you throw something forward, it is already traveling at the speed of the train and you add some more force from your arm and this adds to it's current speed so it goes forward.

this is true except for light supposedly, ie the infamous light speed, light speed can't add to other stuff, shine a light on a train or on the ground and it won't get there any quicker cause it's instant. But then why does light from the closest star take 50 years to get here??? idk

We are on a rock that spins through space at thousands of miles per hour but we don't feel or notice a thing. birds fly and we jump, get in airplanes and even launch to the moon as the space ship orbits earth at thousands of mph, as the earth moves forward at a high speed the shuttle stays with it and the solar system and universe are all moving too.

Answer 3

Speed is always relative. When you say that the fly is flying at 30kmph, you really mean that its speed is 30kmph more than the speed of the jet. When you say that the jet is flying at 1000kmph, you really mean that it is moving at 1000 kmph faster than the ground below it. So, the fly's speed, relative to the ground is 1030kmph, but relative to the jet, it is 30kmph.

Answer 4

Not a simple answer. Velocity is relative to a fixed location or point. Relative to the jet, the surface of the earth, the sun/solar system, Milkyway Galaxy, center of the known Universe would all yied different answers each of which would be technically correct.

Answer 5

Average is 1000 kph, varying between 970 kph and 1030 kph depending whether it is flying fore or aft. The fly must turn around at some point!

Answer 6

Relative to the earth below, assuming the jet speed is also relative to the earth below, then 1030 km/hr.

Answer 7

1030 kph

Answer 8

It's all relative,my friend,but factually speaking,he is going 1030kmph...tom science

Answer 9

1030 kmph... easy!

Answer 10

its all relative
