Question

A body travels from rest with acceleration 8m/s^2.find its velocity when it has covered a distance of 100m

Answer 1

U = 0
A = 8
V =?
S = 100

V = u + at

$v {}^{2} = u {}^{2} + 2as$

$v {}^{2} = (0) {}^{2} + 2(8)(100)$

$v {}^{2} = 1600$

$v \: = 40$

$hence \: velocity \: would \: be \: 40mps$
