Question

A car starts from rest and moves with uniform acceleration of 2 metre per second square how much time will it take to cover the distance of 49 metre
​

Answer 1

Explanation:

hope this helps u

Answer 2

Answer:

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

since initial velocity is zero

therefore it=0

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

$2s \div a = {t}^{2}$

98/2 =49

${t}^{2} =49$

$t = 7sec$
