Explanation:
u = 20 kmph = 20*1000/3600 = 200/36 = 5.55 mps
v = 60kmph = 60*1000/3600 = 600/36 = 16.66mps
t = 6s
a = 16.66 - 5.55 / 6
= 11.11 / 6
= 1.85 mps

Explanation:
To find acceleration =Final velocity (v) -Initial velocity (u) /time
According to the question,
Initial velocity =20km/h=20×5/18=5.55556m/s (converting km/h to m/s)
Final velocity =60km/h=60×5/18=16.66667m/s(converting km/h to m/s)
Time given=6 seconds
Acceleration =v-u/t
=16.66667-5.55556/6
=1.85185m/s²
