Explanation:
u= 20 km/h = 20*5/18= 50/9 m/s
v= 60 km/h = 60*5/18= 50/3 m/s
t= 6 s
a= v-u/t
= 50/3-50/9÷6
= 100/9÷6
= 100/9×1/6
= 50/27 m/s^2
=1.85ms2

Answer: initial velocity= 20 km/ hr = 20× 5/18 = 50/9
final velocity = 60 km / hr = 60× 5/18 = 50/3
acceleration= 50/3 - 50/9 ÷ 6 =. 50/27 = 1.85..... m/s2
