Answer:
Sorry dear . Don't Know the answer of this question. But I found a related question of it. Only the velocity is different nor u can use the method showed here. if useful please mark me as brainlist ✌️
Step-by-step explanation:
As the car is starting from the rest,
Initial velocity= u = 0 m/s
Final velocity= v= 54 km/h
To convert km/h to m/s, we multiply it by 5/18 .
Final velocity= v= 54 km/h = 54 × 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/s ^2 (Square)
s= Distance travelled
Equation of motion :
s= ut + 1/2 at ^2 (Square)
= 0+ 1/2 × 7.5× 2^2 (square)
= 15 meters .
