Question

a car starts from rest and attains a velocity of 10 km/h in 2 seconds find acceleration in si units​

Answer 1

HEYA ❣️

(u)Initial velocity=0m/s ( starts from rest )

(v)Final velocity = 10 km/h = 2.78 m/s

(t) time taken = 2 sec

acceleration=(v-u)/t

a=(2.78-0)2

a= 2.78/2

a = 1.39 m/s²

Answer 2

Given : u = 0 , v=10000 m/3600 s = 2.77 m / s. , t= 2 s

Acceleration = (v - u) / t

A = (2.77 - 0) / 2

A = 2.77 ÷ 2

A = 1.39 m/s^2

Answer

1.39 m/s^2
