Explanation:
Initial speed = u = 18 km/hr = 5 m/s
Final sped = v = 36 km/hr = 10 m/s
acceleration a = (v-u)/t = (10-5)/5 = 1 m/s2
Distance travelled S = u t + (1/2) a t2 = 5×5 + (1/2)×1×52 = 37.5 m

Explanation:
initial speed =18km
final speed=36km
time taken=5seconds
acceleration=v=u+at
36=18+5a
36-18=5a
18=5a
a=18/5=3.6km/h
