Answer:
The acceleration is 466.7m/s^2
Step-by-step explanation:
Given
[tex]u = 0m/s[/tex] -- Initial Velocity
It is 0 because the plane starts from a standstill
[tex]v = 350mi/h[/tex] -- final velocity
[tex]t = 45s[/tex] -- time
Required
Determine the acceleration
This is calculated using Newton's first equation of motion
[tex]v = u + at[/tex]
Convert time to hour
[tex]t = 45s[/tex]
[tex]t = \frac{45}{60}hr[/tex]
[tex]t = 0.75hr[/tex]
Substitute values for v, u and t
[tex]350 = 0 + a*0.75[/tex]
[tex]350 = 0.75a[/tex]
Divide both sides by 0.75
[tex]\frac{350}{0.75} = a[/tex]
[tex]466.67 = a[/tex]
[tex]a=466.67m/s^2[/tex]
Hence, the acceleration is 466.7m/s^2
