B) - 1m/s^2

Explanation:

Final speed = 0 m/s

Initial speed = 5m/s

Time taken for it to come to rest (0m/s) = 5

then use the formula;

[v = u + at], where v is the final speed ... u is the initial speed ... t is time taken for it to come to rest and a is the acceleration

; 0 = 5 + 5a

; - 5 = 5a

; Acceleration = - 1 m/s^2
