Question

A body starts from rest and travels and 18 m in 5th second. find accelaration

Answer 1

Answer:

$18 \div 5 = 3.6m \: per \: second$

Answer 2

Answer:

starts from rest so u=0

Snth=18( distance in nth second)

t=5

a=?

Snth=u+a/2(2n_1)( equation of motion)

18=0+a/2(2×5_1)

36= 9a

36/9 =a

a=3m/s^2
