Answer:
10.92 m/s²
Explanation:
Applying,
s = ut+at²/2.................... Equation 1
Where s = distance. u = initial velocity, t = time, a = acceleration.
From the question,
Given: s = 400 meters, t = 8.56 seconds, u = 0 meters/seconds (Starts from rest)
Substitute these values into equation 1
400 = 0(8.56)+a(8.56²)/2
400 = 73.2736a/2
73.2736a = 800
a = 800/73.2736
a = 10.92 m/s²
