Morbid means to be appealed to death,
Retrospection means a look into the past.
We can infer she avoids Morbid Retrospection due to a rough past that could have caused PTSD (Post Traumatic Stress Disorder). Someone could have died in her past that was close to her.
initial velocity, u = 0m/s (starts from rest)
final velocity, v = ?
time, t = 10 seconds
acceleration, a = 0.8m/s²
v - u = at
v - 0 = 0.8(10)
v - 0 = 8
v = 8m/s
speed = distance / time
distance = speed x time
distance = 8 x 10
distance = 80m
