Answer:
1481.48 meters
Explanation:
first convert speed to meters
now, find the time taken for coming at rest
u - v / a = (-200/9)/(-1) = 200/9 seconds
now find the answer by second equation of motion
ut + at²/2 = (400/9)(400/9) + {-1(400/9)²/2} = 160000/81 - 40000/81 = 120000/81 = 40000/27 = 1481.48 meters
