The acceleration is 466.7m/s^2

Step-by-step explanation:

Given

u = 0m/s -- Initial Velocity

It is 0 because the plane starts from a standstill

v = 350mi/h -- final velocity

t = 45s -- time

Required

Determine the acceleration

This is calculated using Newton's first equation of motion

v = u + at

Convert time to hour

t = 45s

$t = \frac{45}{60}hr$

t = 0.75hr

Substitute values for v, u and t

350 = 0 + a*0.75

350 = 0.75a

Divide both sides by 0.75

$\frac{350}{0.75} = a$

466.67 = a

a=466.67m/s^2

Hence, the acceleration is 466.7m/s^2
