It won't happen anything i think it will just be a something like a small thing
Given parameters:
Displacement = 8km
Velocity = 3.8km/h
Unknown:
time = ?
Solution:
Velocity is displacement divided by time.
Velocity =
Displacement = velocity x time
Input the parameters:
8 = 3.8 x time
Time =
= 2.1s
The time taken is 2.1s
The frequency of the wave is the frequency of that sine function ... 2,000π ... but that's the <u>angular </u>frequency, in radians per second.
To convert angular frequency to Hz, we have to divide by 2π.
So the frequency of this wave is <em>1,000 Hz. </em>
Answer:
acceleration: 5.48 m/s²
time taken: 9.3 seconds
Given:
- mass: 1200 kg
- force: 6572 N
- initial velocity: 15 m/s
- final velocity: 66 m/s
<u>using the formula's</u>:
<u>answer 1</u>:
![\sf acceleration = \dfrac{F}{m}](https://tex.z-dn.net/?f=%5Csf%20acceleration%20%3D%20%20%5Cdfrac%7BF%7D%7Bm%7D)
![\sf acceleration = \dfrac{6572 }{1200 }](https://tex.z-dn.net/?f=%5Csf%20acceleration%20%3D%20%5Cdfrac%7B6572%20%7D%7B1200%20%7D)
![\sf acceleration = 5.4766... \ m/s^2](https://tex.z-dn.net/?f=%5Csf%20acceleration%20%3D%205.4766...%20%5C%20m%2Fs%5E2)
// rounded to nearest hundredth //
<u>answer 2</u>:
![\sf time \ taken = \dfrac{\Delta v}{a}](https://tex.z-dn.net/?f=%5Csf%20time%20%5C%20taken%20%3D%20%20%5Cdfrac%7B%5CDelta%20v%7D%7Ba%7D)
![\sf time \ taken = \dfrac{66 - 15}{5.48}](https://tex.z-dn.net/?f=%5Csf%20time%20%5C%20taken%20%3D%20%5Cdfrac%7B66%20-%2015%7D%7B5.48%7D)
![\sf time \ taken = 9.3122 \ seconds](https://tex.z-dn.net/?f=%5Csf%20time%20%5C%20taken%20%3D%209.3122%20%5C%20seconds)
// rounded it to nearest tenth //
