The acceleration of the jet is 11.4 m/s^2

Explanation:

Since the jet motion is a uniformly accelerated motion (=constant acceleration), we can use the following suvat equation:

v^2-u^2=2as

where

v is the final velocity

u is the initial velocity

a is the acceleration

s is the displacement

For the jet in this problem, we have

u = 0 (it starts from rest)

v = 40 m/s (final velocity)

s = 70 m (length of the runway)

Solving for a, we find the acceleration:

a=\frac{v-u}{t}=\frac{40^2-0}{2(70)}=11.4 m/s^2

What is the magnitude of a vector with components (15 m, 8 m)?
il63 [147K]
The answer is 17 m because you have to add the 15 m and the 8 m together to get the answer so it will be like this 17x17 = 15x15 + 8x8 got it?

Mary pushes a crate by applying force of 18 newtons. Unable to push it alone, she gets help from her friend, Anne. Together they
defon
This problem is relatively simple, in order to solve this problem the only formula you need to know is the formula for friction, which is: 

<span>Ff = UsN </span>

<span>where Us is the coefficient of static friction and N is the normal force. </span>

<span>In order to get the crate moving you must first apply enough force to overcome the static friction: </span>

<span>Fapplied = Ff </span>

<span>Since Fapplied = 43 Newtons: </span>

<span>Fapplied = Ff = 43 = UsN </span>

<span>and it was given that Us = 0.11, so all you have to do is isolate N by dividing both sides by 0.11 </span>

<span>43/0.11 = N = 390.9 which is approximately 391 or C. 3.9x10^2</span>

A woman weighs 129 lb. If she is standing on a spring scale in an elevator that is traveling downward, but slowing up, the scale
Lena [83]

Answer:

C) less than 129 lb.

Explanation:

Let the elevator be slowing up with magnitude of a . That means it is accelerating downwards  with magnitude a .

If R be the reaction force

For the elevator is going downwards with acceleration a

mg - R = ma

R = mg - ma

R measures its apparent weight . Spring scale will measure his apparent weight.

So its apparent weight is less than 129 lb .

Consider an air parcel at latitude = 18◦N, moving northward (conserving absolute vorticity), with initial relative vorticity = 5
mariarad [96]

Answer:

relative vorticity is  -0.868 × 10^{-5} s-1

Explanation:

given data

air parcel at latitude = 18◦N

relative vorticity = 5.8 × 10^−5 s−1

to find out

relative vorticity

solution

we will apply here conservation of vorticity that is

ζ + f = constant

we know ζ initial = 2Ωsin(5π/18)

and  f initial = 5.8 × 10^{-5}

and f final =  2Ωsin(π/18)

and here angular frequency Ω = 0.7272 × 10^{-4} s-1

its mean

ζ initial -  ζ final = f final - f initial

so

ζ final =  ζ initial - f final + f initial

ζ final =  - 2Ωsin(5π/18) + ( 2Ωsin(π/18) +  5.8 × 10^{-5}  )

ζ final =  - 2(0.7272 × 10^{-4}) sin(5π/18) + ( 2(0.7272 × 10^{-4})sin(π/18) +  5.8 × 10^{-5}  )

ζ final = -0.868 × 10^{-5} s-1

so relative vorticity is  -0.868 × 10^{-5} s-1
