Question

An object starts from rest . It moves with uniform acceleration and in 8seconds it travels 95 metres .Find out it's acceleration.

Answer 1

solution:

Here we have ;

u = 0m/s

s = 95 m

t = 8 seconds

As, S = ut + 1/2 at^2

=> 95 = 0×8 + 1/2 × a × 64

=> 95 = 32a

=> a = 2.96 [Approx 3 ]

$thus \: acceleration \: = 3 \frac{m}{ {s}^{2} }$

Answer 2

Hey!!!!

$given$

$u = 0 \frac{m}{s}$
$t = 8sec$
$s = 95m$

Therefore,
$by \: second \: {equ}^{n} \: of \: motion$
$s = ut + \frac{1}{2}a {t}^{2}$

putting all the given values in the equation...

$95 = (0)(8) +( \frac{1}{2})a(8)^2$
$95 = (\frac{1}{2})64a$
$95 = 32a$
$a = \frac{95}{32}$
$a = 2.96 \frac{m}{ {s}^{2} }$

$therefore$

$a = 3 \frac{m}{ {s}^{2} } {approx}$
