An airplane on a runway accelerates at 4.0 meters/second2 for 28.0 seconds before takeoff. how far does the plane travel on the runway before takeoff?

1568m

Explanation:

An airplane on a runway accelerates at 4.0 meters/second2 for 28.0 seconds before takeoff. How far does the plane travel on the runway before takeoff?

Motion is he change in position of an object with respect to time.

velocity:is the displacement change with respect to time

distance is

From newton's equation of motion

S=ut+1/2at^2

We assume that the airplane is starting from rest

at rest u ,initial velocity becomes 0

a, acceleration 4m/s^2

t, time=28secs

we superpose into the equation, we have

S=0*4+0.5*4*28^2

S=1568m

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
