Question

A body is uniformly accelerated from rest with 4m/s^2 find displacement in 10 seconds

Answer 1

Howdy!!

your answer is ------

Given, acceleration a = 4m/s^2
& time period t = 10sec
body is start from rest

so, initial velocity u = 0

now, according to formula ,

$s = ut + \frac{1}{2} a {t}^{2}$
$s = 0 \times 10 + \frac{1}{2} \times 4 \times {10}^{2} \\ = > s = 0 + 2 \times 100 \\ = > s = 200m$

hence, displacement is 200meter

hope it help you
