Step-by-step explanation:
initial velocity (u) = 18km/h
= 18x1000/60x60 m/s
= 5 m/s
final velocity (v) = 36km/h
= 36x1000/60x60 m/s
= 10 m/s
time ( t) = 5 minutes = 5x60 = 300 sec
acceleration = ( final velocity - initial velocity)/time
a = ( v - u)/t
a = (10 - 5)/300
a = 5 / 300 m/s^2
a = 1/60 m/s^2
