Question

a car travels from rest at 20km in 6 second fro. rest.what is acceleration​

Answer 1

Answer:

by second equation of motion

$s = ut + \frac{1}{2} a {t}^{2} \\ initial \: velocity \: is \: zero \\ 20000 = \frac{1}{2}a {(6)}^{2} \\ a = 1111.12$

hope the answer will help you

Answer 2

Answer:

Explanation:u=0.

D=20km t=6sec

V=d/t

V=20/6=10/3

V=u+at

10/3=0+a*6

10/3*6=a

10/18=a
