given
u=18km/h=18×5÷18=5m/s
v=36km/h =36×5÷18=10 m/s
t=5 sec
a= v-u÷t
10-5÷5=1m/s^2
therefore acceleration of car is 1m/s^2
u=18km/h=18×5÷18=5m/s
v=36km/h =36×5÷18=10 m/s
t=5 sec
a= v-u÷t
10-5÷5=1m/s^2
therefore acceleration of car is 1m/s^2

Explanation:
Acceleration = (Final Vel. - Initial Vel. ) / Time
Acceleration = (10 m/s - 5 m/s) / 5s
Acceleration = 5 m/s / 5s
Acceleration = 1 m/s²
