Acceleration is given by
a = (v - u)/t
-2 m/s² = (0 - u)/10 s
[Negative sign because it’s retardation]
-20 m/s = -u
u = 20 m/s
∴ Initial velocity of car is 20 m/s
a = (v - u)/t
-2 m/s² = (0 - u)/10 s
[Negative sign because it’s retardation]
-20 m/s = -u
u = 20 m/s
∴ Initial velocity of car is 20 m/s
