HOLA MATE YOUR ANSWER IS HERE:
acceleration = change in velocity/time
here's change in velocity = V2 - V
= 36-18 = 18 km/h = 18×5/18m/s = 5 m/s
1)so, acceleration will be:
a = 5/5 = 1 m/sec^2
2) according to the equation of motion:
s = ut + 1/2at^2
= 5×5 + 1×5×5/2
= 25 + 12.5 = 37.5m
s = 37.5 m
HOPE THIS HELPS YOU ✌️✌️

u= 5m/s
v=10m/s
t=5s
a=1m/s^2
s=37.5 m
