Initial velocity of the car (u) = =
Final velocity (v) = 0 m/s
Time = 15s
________________________
Use this equation
v = u + at
0 = 16.67 + a(15)
15 a = -16.67
15 will shift
Divide it
a =
The retardation of the car =

ANSWER:-
➣
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
Given:-
• Intial velocity of the car (u) =
Final velocity (v) =
Time =
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
• SOLUTION:-
We know:-
• Putting the values:-
0 = 16.67 + a[15]
0 = 16.67 + 15a
15 a = -16.67
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
Therefore, the Retardation of the car is:
