Answer:

HI there !!!

Here ,

As the car is starting from rest ,

Initial velocity = u = 0 m/s

Final velocity = v = 54 km/hr

To convert km/hr to m/s , we multiply it by 5/18

Final velocity = v = 54 km/hr = 54 x 5/18

= 15 m/s

Time = t = 2 sec

a = acceleration

Equation of motion :

v = u + at

15 = 0 + 2a

a = 15/2 = 7.5 m/s²

s = distance traveled

Equation of motion :

s = ut + 1/2 at²

= 0 + 1/2 × 7.5 × 2²

= 15 metres
