Hi !
Initial velocity = u = 20 km/hr = 20*5/18 = 5.5 m/s
Final velocity = v = 60 km/hr = 16.66 m/s
time = t = 60 sec
acceleration = a
a = v-u/t
= 16.66-5.5/60
= 11.16/60
= 0.186 m/s²

U = 20km/hr = 50/9m/s
V = 60km/hr = 50/3m/s
T = 60s
A = v - u/ t
50/3 - 50/9 / 60
100/9 * 1/60
A = 0.12m/s square
V = 60km/hr = 50/3m/s
T = 60s
A = v - u/ t
50/3 - 50/9 / 60
100/9 * 1/60
A = 0.12m/s square

Sorry the answer is 0.18m/s square
