Question

starting from rest a car travels 18m in 3 sec. Find its acceleration.​

Answer 1

Explanation:

hope it's correct........

Answer 2

GIVEN:

initial velocity (u)= 0

distance (s)=18 m

time(t)=3 sec

TO FIND:

acceleration (a)=??

SOLUTION:

$s = ut + \frac{1}{2} a {t}^{2}$

$s = \frac{1}{2} a {t}^{2}$

$a = \frac{2 \times 18}{9} \\ a = 4 \frac{m}{ {s}^{2} }$

I hope this helps ( ╹▽╹ )
