Verified answer
Initial velocity u = 0 km/hr
= 0 m/s
Final velocity v = 36 km/hr * 5/18
= 10 m/s
Time T = 40 s
Acceleration = (v - u)/T
= (10-0)/40
= 1/4
= 0.25 ms-2
[tex]Distance = ut + 1/2 a {t}^{2} [/tex]
Distance = 0 + 1/2*0.25*40*40
Distance = 0 + 1/2*0.25*1600
Distance = 0 + 0.25*800
Distance = 0 + 200
Distance = 200 m
Hope it helps
