Answer:
c) - 0.5 m/s²
Explanation:
U (initial velocity) = 10 m/s
V (final velocity) = 0 m/s
t (time taken) = 20s
a (acceleration) = (V – U) / t
a = 0 – 10 / 20
a = – 0.5 m/s2
Retardation = 0.5 m/s2

Answer:
Third option is correct
Explanation:
Given :
u = 10m/s, t = 20s, v = 0m/s
To find :
a = ?
[a will be negative as it is retardation]
Solution :
We, know that, v = u + at
0 = 10 + 20a
20a = -10
a = -1/2 m/s² = -0.5 m/s2
