Answer:
The required solution is 100890 Pa and 14.3lb/in²
Explanation:
See attached image
acceleration of car is 1.8 m/s^2
time = 14 s
initial speed = 14 m/s
so the final speed is calculated by



so the total distance moved in this interval of time is



now the average speed is given as



so the average speed will be 26.6 m/s
For any periodic wave
<span>v = f λ </span>
<span>where </span>
<span>v = velocity </span>
<span>f = frequency </span>
<span>λ = wavelength (distance between 2 successive crests) </span>
<span>This means that </span>
<span>λ = v/f </span>
<span>Assuming that v stays the same while f increases, λ must DECREASE.
I hope this helps
