Question

What is the acceleration in m/s2, if the body starts from rest and travels a distance of ‘s’ m in 2 seconds? *

Answer 1

Answer:

s/4

Explanation:

first we will find the velocity v

v=d/t

v=s/2

u=0 as the body starts from rest

t=2sec

a=v-u/t

a=s/2-0/2

a=s/4  

Answer 2

The answer is (s/4) m/s²

GIVEN

Body starts from rest and travels a distance of ‘s’ m in 2 seconds.

TO FIND

Acceleration in m/s²

SOLUTION

The above problem can be solve as follows;

Acceleration can be defined as change in velocity in a given amount of time.

a = (v-u)/t

Where,

a = acceleration

u = Initial velocity

v = final velicity

t = time taken

Given,

Initial velovity, u = 0 (body starts from rest)

Distance travelled = s

time taken = 2 seconds

Therefore,

Final velocity, v = Distance/Time

v = s/2

Acceleration can be calculated as;

$a = \frac{ \frac{s}{2} - 0 }{2}$

a = (s/4) m/s²

Hence, The answer is (s/4) m/s²
