Question

The Peregrine falcon is the fastest bird being able to reach a max velocity of 322 km/hr (just about 90 m/s). Let’s say that on average this bird takes about 10 seconds to reach that max velocity. If the falcon is able to keep that velocity constant for another 10 seconds how far would the falcon travel? (G.A.R.)

Answer 1

i need help asap pleaseeeee

Answer 2

so to get the right answer i think you can use the rule of 3 simple
than this bird after get this velocity of 90 m/s and keep it again 10 second so to get the distance what will travel in this 10 second with this velocity you can writing

90 m travel in 1 sec.
x m travel in 10 sec so cross multiplie and calcule the x value

x = 90*10/1 = ? m


hope helped understandably

Answer 3

yes thank you

Answer 5

yw . np. @unknown102920 was my pleasure and anytime

Answer 6

I think that this question can have multiple answers depending on how you interpret it.

Answer 7

really ?

Answer 8

@Vocaloid please your opinion ?

Answer 9

In this example, the distance and displacement would be the same since the velocity is always positive (the falcon is not changing its direction). So we can say that the distance traveled will be the area under the velocity-time graph.

Answer 10

so i think with this graph of area you made it so much complex this problem - and i dont know again the student who asked - posted this problem in what classe of study learn

Answer 11

so just bc. than we use this graph about what you talk - my opinion - that this is learned in a high school or ... class of study - how you think it ?

Answer 12

@unknown102920 in what class you learn please ?

Answer 13

Depending upon the acceleration the answer could vary.

If the falcon accelerates linearly between 0sec and 10secs your velocity-time graph would look like this-

the shaded area is your distance traveled.

but If the falcon accelerates non uniformly between 0sec and 10secs your velocity-time graph would look like this-

The area under both graphs is different. Even though they both perfectly fit the problem statement. So you can have different answers depending upon the type of acceleration

Answer 14

If you haven't studied calc, you can assume the acceleration to be linear.

Answer 15

- please re-read this : If the falcon is able to keep that velocity constant for another 10 seconds how far would the falcon travel?

write there : keep the velocity CONSTANT - yes ? so in this case what we need to do again ?

Answer 16

but yes you are right than we dont keep in mind this word of CONSTANT - so may be very complex this problem - i believe you

Answer 17

time = 0 to time = 10: the falcon goes from 0 to 90m/s. Which means that it accelerates
the falcon is now at 90m/s.

time = 10 to time = 20: the falcon will keep flying at 90m/s (constant velocity)

Yes, we don't need to assume constant acceleration.

ty @imqwerty all your work and idea

Whoops, I meant *constant not linear (-:
