Explanation / Answer

here,

the initial speed , u = 8.7 m/s

final speed , v = 31.1 m/s

t = 0.041 s

let the accelration be a

v= u + a * t

31.1 = 8.7 + a * 0.041

a = 546.3 m/s^2

the distance of accelration , s = u * t + 0.5 * a * t^2

s = 8.7 * 0.041 + 0.5 * 546.3 * 0.041^2

s = 0.82 m

the distance travelled is 0.82 m
